RTL8852BE fw security fail then lost WIFI function during suspend/resume cycle

[Hui Wang]

[Impact]

On a Dell laptop, When we do suspend/resume test, we found the
realtek wifi couldn't work after resume, from the dmesg, we found
the error log as below:
Log:
三 05 15:08:02 u-Precision-3591 kernel: rtw89_8852be 0000:02:00.0: fw security fail
三 05 15:08:02 u-Precision-3591 kernel: rtw89_8852be 0000:02:00.0: download firmware fail
三 05 15:08:02 u-Precision-3591 kernel: rtw89_8852be 0000:02:00.0: [ERR]fwdl 0x1E0 = 0x62
三 05 15:08:02 u-Precision-3591 kernel: rtw89_8852be 0000:02:00.0: [ERR]fwdl 0x83F2 = 0x8

[Fix]

Backport a commit from mainline kernel (linux-next), this will retry firmware
loading for 5 times.

[Test Case]

run suspend/resume test case for over 100 times, the wifi still
works.

[Where problems could occur]

This commit comes from mailine kernel, and it doesn't change existing
driver except loading firmware a couple of more times if there is an error.
In theory this will not introduce regression.

This bug is awaiting verification that the linux/6.8.0-32.32 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux' to 'verification-done-noble-linux'. If the problem still exists, change the tag 'verification-needed-noble-linux' to 'verification-failed-noble-linux'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
