pstore: Fix leaked pstore_record in pstore_get_backend_records()
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.
Fixes: 2a2b0acf768c ("pstore: Allocate records on heap instead of stack")
