[PATCH 5.15.y 0/1] Fix of CVE-2023-52904 for stable-5.15

[Harshvardhan Jha <harshvardhan.j.jha@xxxxxxxxxx>]

Folowing is a backport of commit  a474d4ad59cd ("ALSA: usb-audio: Fix
possible NULL pointer dereference in snd_usb_pcm_has_fixed_rate()") to
stable-5.15 branch which fixes broken commit bfd36b1d1869 ("ALSA:
usb-audio: Always initialize fixed_rate in
snd_usb_find_implicit_fb_sync_format()").

This was a clean pick and shouldn't be break anything. Basic smoke tests
were performed on this patch.
