Xenial update: v4.4.230 upstream stable release

[Kamal Mostafa]

SRU Justification

    Impact:
       The upstream process for stable tree updates is quite similar
       in scope to the Ubuntu SRU process, e.g., each patch has to
       demonstrably fix a bug, and each patch is vetted by upstream
       by originating either directly from a mainline/stable Linux tree or
       a minimally backported form of that patch. The following upstream
       stable patches should be included in the Ubuntu kernel:

       v4.4.230 upstream stable release
       from git://git.kernel.org/

btrfs: cow_file_range() num_bytes and disk_num_bytes are same
btrfs: fix data block group relocation failure due to concurrent scrub
mm: fix swap cache node allocation mask
EDAC/amd64: Read back the scrub rate PCI register on F15h
mm/slub: fix stack overruns with SLUB_STATS
usb: usbtest: fix missing kfree(dev->buf) in usbtest_disconnect

hwmon: (acpi_power_meter) Fix potential memory leak in acpi_power_meter_add()
virtio-blk: free vblk-vqs in error path of virtblk_probe()
i2c: algo-pca: Add 0x78 as SCL stuck low status for PCA9665
Revert "ALSA: usb-audio: Improve frames size computation"
SMB3: Honor 'seal' flag for multiuser mounts

cifs: Fix the target file was deleted when rename failed.
MIPS: Add missing EHB in mtc0 -> mfc0 sequence for DSPen
