Subject: pstore: Fix leaked pstore_record in pstore_get_backend_records()

From: Douglas Anderson <[email protected]>

commit f6525b96dd9f68efe374e5aef864975e628de991 upstream.

When the "if (record->size <= 0)" test is true in pstore_get_backend_records() it's pretty clear that nobody holds a reference to the allocated pstore_record, yet we don't free it.

Let's free it.
