pstore/platform: fix potential mem leak if pstore_init_fs failed
[ Upstream commit 8a57d6d4ddfa41c49014e20493152c41a38fcbf8 ]
There is a potential mem leak when pstore_init_fs failed,
since the pstore compression maybe unlikey to initialized
successfully. We must clean up the allocation once this
unlikey issue happens.
