[PATCH] btrfs: abort transaction in do_remap_reloc_trans() on failure

[Mark Harmstone <mark@harmstone.com>]

If one of the calls made by do_remap_reloc_trans() fails, we can leave
the remap tree in an inconsistent state. Abort the transaction if this
happens, to prevent the corrupt state from reaching the disk.
