[PATCH 5.10 030/717] ASoC: qcom: fix unsigned int bitwidth compared to less than zero

[ Upstream commit bcc96dc3cf8048c80af7c487af17e19be27ac57d ]

The check for an error return from the call to snd_pcm_format_width
is never true as the unsigned int bitwidth can never be less than
zero. Fix this by making bitwidth an int.
