MLK-12771: ASoC: fsl_asrc: fix dma task timeout issue
The test case is one p2p playback + two m2m converter running
simultaneously. There are three root cause for this issue:
1. hw_free() of p2p may be called twice in the end, which cause
release twice of one pair, if another pair request is called between
this two release, there will be issue.
2. In m2m close(), the asrc_priv->pair[i] will be set NULL twice,
which is same issue as 1.
3. when output rate is more than eight multiple of input rate for m2m,
the last_period_size should be larger.
