Bug Description

[SRU Justification]

[Impact]
With the rtl8723bu Wi-Fi/Bluetooth combo adapter, if the wifi is turned
off and then turned on again under the circumstance that a Bluetooth
device was paired previously, the system can't connect to a wireless
network until the system is rebooted.

[Fix]
Commit e542e66b7c2e("rtl8xxxu: add bluetooth co-existence support for
single antenna"), which landed v5.5 and as its subject suggests, support
bluetooth co-existence for RTL8723BU and fixes WiFi disconnection
problem when Bluetooth is in action.

Commit a9bb0b515778("rtl8xxxu: Improve TX performance of RTL8723BU on
rtl8xxxu driver") was added as a prerequisite to aforementioned fix.

Commit 4fcef8609132("rtl8xxxu: remove set but not used variable
'rate_mask'") and commit eac08515d7bd("rtl8xxxu: Remove set but not used
variable 'vif','dev','len'") are included as minor fixes to previous
commits.

[Test Case]
1. Turn on Wi-Fi and get associated with some AP.
2. Pair some bluetooth device.
3. Turn off Wi-Fi and turn again.
4. Expect Wi-Fi reconnects to the previous associated AP.

[Regression Potential]
Low. Both commits only affect RTL8723BU.

========== Original Bug Description ==========

With the rtl8723bu wireless adapter, if the wifi is turned off and then turned on again, the system can't connect to a wireless network until the system is rebooted.
The issue is not upstream. With mainline kernel and in other distros, everything works fine.

Please have a try my PPA at https://launchpad.net/~vicamo/+archive/ubuntu/ppa-1878296. It's still compiling and may take a few more hours to complete. To install kernel packages from it:

  $ sudo add-apt-repository ppa:vicamo/ppa-1878296
  $ sudo apt install linux-modules-extra-5.4.0-31-generic=5.4.0-31.35+lp1878296

This should install several kernel packages, and then please reboot into this kernel and check if the problem is gone, leave a message here so that we can continue to backport the fix.

Installed the kernel packages and rebooted. Everything worked fine.

The fixing patches are in v5.5, so this affects linux-generic of B/E/F and linux-oem-osp1 in B. Groovy is still with v5.4 -generic kernel, so it's included for now.
