[bwn] always allocate maximum size txhdr entries; prepare for fw 598

* always allocate maximum size txhdr entries
* set the right rx header offset/framesize based on firmware

This still isn't what's completely required for fw 598 support; there's
more to come.

Tested:

* Apple BCM94321MC 11abgn NIC, 11a STA mode, firmware version 4xx.

Obtained from:	DragonflyBSD (txhdr entry sizing), fw 598 RX header size (linux b43)
