qla2xxx: Fix virtual port failing to login after chip reset.

BugLink: http://bugs.launchpad.net/bugs/793702

commit cefcaba67ab97fb756b3a6af5139c94d861b660d upstream.

This patch ensures qla82xx_watchdog is not being run for the vport. It also
makes sure that beacon ON is not done for the vport, as it will lead to the
waking up of the dpc thread again and again.
