Subject: [PATCH v2] ocfs2: Reomve err less than zero check

Because enum dlm_status starts from 0, the check for err < 0 is always
false.

Clean up the following coccicheck warning:

fs/ocfs2/dlm/dlmdebug.c:222 dlm_errname() warn: unsigned 'err' is never
less than zero.

fs/ocfs2/dlm/dlmdebug.c:214 dlm_errmsg() warn: unsigned 'err' is never
less than zero.
