ASoC: pcm: Drop incorrect double/extra frees

commit 017d9491ce203c620ad1377f46a3ce78d554b2de upstream.

The changes in "ASoC: pcm: free path list before exiting from error
conditions" actually introduced both double frees (in case where the
path list was allocated but empty) and frees of unallocated memory (in
cases where the error being handled was -ENOMEM.  Drop the commit for
now.
