[XFS] XFS: Check for valid transaction headers in recovery

When we are about to add a new item to a transaction in recovery, we need
to check that it is valid first. Currently we just assert that header
magic number matches, but in production systems that is not present and we
add a corrupted transaction to the list to be processed. This results in a
kernel oops later when processing the corrupted transaction.

Instead, if we detect a corrupted transaction, abort recovery and leave
the user to clean up the mess that has occurred.
