unhandled firmware response in iwm0

[Jan Schreiber]

Hi,

when connecting to an open wifi I get following message:

iwm0: unhandled firmware response 0xce/0xb800002c rx ring 0[48]

I added another case which ignores the IWM_BT_PROFILE_NOTIFICATION.
I didn't notice any change when connecting, except that the message is
gone.
