Subject: [PATCH] fs: ocfs: remove unnecessary assertion in dlm_migrate_lockres

In the only caller of dlm_migrate_lockres() - dlm_empty_lockres(),
target is checked for O2NM_MAX_NODES.  Thus, the assertion in
dlm_migrate_lockres() is unnecessary and can be removed.  The patch
eliminates such a check.
