pcm: rate - fix the crash in snd_pcm_rate_may_wait_for_avail_min()

Browse source 
The pcm argument passed to the conversion function in
snd_pcm_plugin_may_wait_for_avail_min_conv() should be
pcm->fast_op_arg.

Test command: arecord -Dplughw:x -r12000 -c2 -fS16_LE -M temp.wav

Fixes: d9dbb57b ("pcm: rate - rewrite the may_wait_for_avail_min callback for the rate plugin")
