btrfs: reset RO counter on block group if we fail to relocate

With the automatic block group reclaim code we will preemptively try to
mark the block group RO before we start the relocation.  We do this to
make sure we should actually try to relocate the block group.

However if we hit an error during the actual relocation we won't clean
up our RO counter and the block group will remain RO.  This was observed
internally with file systems reporting less space available from df when
we had failed background relocations.

Fix this by doing the dec_ro in the error case.
