msm: qdsp5: Fix for crash in mp3 driver

When resource allocation fails during mp3 playback, a crash
is observed. When such failure occurs, the driver tries to
access a handle that was never initialized. This is due
to missing flag check to determine whether there was any
memory allocation or not prior to failure. Added flag in error
cases to avoid such issues.
