Wonder why this dumps core.

And iwlwifi(4) then is no different. I think trying to re-attach iwm(4)
in this setup should first work before we try to swap drivers.
again, yet despite the I/O error pciconf now shows:
[~] doas pciconf -lBbcevV pci0:0:20:3

vendor = 'Intel Corporation'
device = 'Cannon Point-LP CNVi [Wireless-AC]'
class = network
bar [10] = type Memory, range 64, base 0xea238000, size 16384, disabled
I wonder why the BAR is disabled but iwlwifi could have done that on attach
fail given it was still enabled after iwm(4) detach.
