btrfs: do not BUG_ON() on failure to update inode when setting xattr
We are doing a BUG_ON() if we fail to update an inode after setting (or
clearing) a xattr, but there's really no reason to not instead simply
abort the transaction and return the error to the caller. This should be
a rare error because we have previously reserved enough metadata space to
update the inode and the delayed inode should have already been setup, so
an -ENOSPC or -ENOMEM, which are the possible errors, are very unlikely to
happen.
So replace the BUG_ON()s with a transaction abort.
