If things keep working ignore them.  If not provide better information
like debug msgs with sysctl debug.iwi set to something like 2 or 3.

The iwi driver in head has a known issue where the firmware will toss
it's cookies if you try to send it a cmd while it's scanning.  The linux
driver sends an explicit abort cmd but the freebsd driver does not (yet)
do that.  However the freebsd driver just picks up from the firmware
error by reseting the card and continuing on.  I have a 2915 card in a
laptop running stable (w/ the driver from head) and I routinely use it
w/ WPA w/o problems (except for highly variable tx performance which is
not something the driver has control over).
