Increase iwx(4) command queue size. Otherwise the firmware sends duplicate
"command done" notifications for earlier commands and then crashes.
There might be an underlying issue that we still need to figure out. But as
of this change the device becomes functional with -48 firmware, which is a
good first step towards switching to -48 firmware eventually.
Tested by jcs@, sven falempin, and myself.
