MLK-10048-3: ASoC: fsl_asrc: fix asrc crach when suspend/resume

merge 7e1a620a030d17f93fdd97d076f1cdd042e79337

The reason of crach is that some variables are not protected in
function mxc_asrc_suspend(), when suspend, there is possibility to
access one NULL pointer.
Refine the spin lock usage, add protecting for pair_hold.
