ASoC: msm: fix the target crash due to the NULL pointer dereference

During the close of the FE, the mclk is disabled which accesses the
codec drv data.
In case if the tapan codec was not initialized, then close sequence
will result in the null pointer dereference.
Fix by adding a null check before accessing the codec data structure.
