net/fm10k/base: reset multicast mode when deleting lport

Deleting lport when multicast mod 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.
