fm10k: Reset multicast mode when deleting lport

Deleting lport when multicast mode is configured to
FM10K_XCAST_MODE_ALLMULTI or FM10K_XCAST_MODE_PROMISC will result in
generating orphaned multicast-group entries in the switch manager.
Before deleting the lport, reset multicast mode to FM10K_XCAST_MODE_NONE
to flush out these multicast-group entries.
