Fix sparse warning:
sound/usb/qcom/qc_audio_offload.c:943:27: sparse: incorrect type in argument 2
expected unsigned int val but got snd_pcm_format_t.

Explicitly cast pcm_format to unsigned int for snd_mask_leave().

Fixes: 326bbc348298 ("ALSA: usb-audio: qcom: Introduce QC USB SND offloading support")
