[9610] wlbt: fix SKB MAC header offset

If A-MSDU is enabled in transmit, the frame is translated
to MSDU sub frame format from Ethernet format.

But the MAC header in SKB is not updated and it causes
access to wrong offset for destination address.

The MAC header offset is corrected in such translation.
