svn commit: r277050 - head/sys/dev/nge

[Pyun YongHyeon]

New Revision: 277050
URL: https://svnweb.freebsd.org/changeset/base/277050

Log:
  Receive filter configuration is done in nge_rxfilter().  Remove
  unnecessary filter configuration code in nge_init_locked().
  While I'm here add a check for driver running state for multicast
  filter handling.  Also remove unnecessary assignment to error
  variable since it is cleared in the function entry.
