Zeng Heng 83baa50939 ASoC: pxa: fix null-pointer dereference in filter() 
[ Upstream commit ec7bf231aaa1bdbcb69d23bc50c753c80fb22429 ]

kasprintf() would return NULL pointer when kmalloc() fail to allocate.
Need to check the return pointer before calling strcmp().

Fixes: 7a824e214e25 ("ASoC: mmp: add audio dma support")
