The UAC1_STR_ATTRIBUTE macro defines configfs show/store handlers for
the fn_play, fn_cap, and fn_cntl string options. The store function
contains an inverted null check on the kstrndup() return value.
This means every write attempt returns -ENOMEM on success and
dereferences a NULL pointer on allocation failure. The attributes
have been broken and unused for many years.
Remove the UAC1_STR_ATTRIBUTE macro and the three attributes it
generated. The internal defaults (FILE_PCM_PLAYBACK, FILE_PCM_CAPTURE,
FILE_CONTROL) set in f_audio_alloc_inst() are unaffected.
