nilfs2: remove unlikely directive causing mis-conversion of error code
The following error code handling in nilfs_segctor_write() function
wrongly converted negative error codes to a truth value (i.e. 1):
err = unlikely(err) ? : res;
which originaly meant to be
err = err ? : res;
This mis-conversion caused that write or sync functions receive the
unexpected error code. This fixes the bug by removing the unlikely
directive.
