[PATCH 3/4] ALSA: usb-audio: qcom: Fix return value in qc_usb_audio_offload_fill_avail_pcms

[wangdich9700]

From: wangdicheng <wangdicheng@xxxxxxxxxx>

The function qc_usb_audio_offload_fill_avail_pcms() always returns -1
regardless of how many PCM devices were successfully filled. This makes
it impossible for callers to know the actual number of available PCMs.

Return the actual count of filled PCM devices instead, which allows
callers to verify that all expected PCMs were properly enumerated.
