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

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.
