btrfs: abort transaction on qgroup failures in create_pending_snapshot()

If we get an error when calling one of the qgroup functions, we jump to
the 'fail' label without aborting the transaction. This is not a bug as up
the call chain (transaction commit path), we will end up aborting the
transaction. However having the explicit transaction abort in
create_pending_snapshot() allows us to get a stack trace and log message
that tells us exactly where we failed, useful for troubleshooting, and
also adds consistency since in that function we abort the transaction in
every other error path.
