Josef Bacik 0df50d47d1 btrfs: abort in rename_exchange if we fail to insert the second ref 
commit dc09ef3562726cd520c8338c1640872a60187af5 upstream.

Error injection stress uncovered a problem where we'd leave a dangling
inode ref if we failed during a rename_exchange.  This happens because
we insert the inode ref for one side of the rename, and then for the
other side.  If this second inode ref insert fails we'll leave the first
one dangling and leave a corrupt file system behind.  Fix this by
aborting if we did the insert for the first inode ref.
