panic booting with if_tap_load="YES" in loader.conf

I just updated from r346856 to r347950 and ran into a new panic, caused
by having if_tap_load="YES" in /boot/loader.conf - because it's already
built-in to the kernel:


module if_tuntap already present!

kernel trap 12 with interrupts disabled


The backtrace is:


vpanic()

panic()

trap_fatal()

trap_pfault()

trap()

calltrap()

--- trap 0xc

_thread_lock()

pmap_delayed_invl_start_u()

pmap_remove()

Uptime: 1s
