Since commit 8437754c83351d6213c1a47ff029c1126d6042a7, ar->fw is expected to be
pointing to memory allocated by vmalloc. If the api1 method (via
ath6kl_fetch_fw_api1) is used to allocate memory for ar->fw, then kmemdup is
used. This patch checks if the firmware being loaded is the 'fw' image, then
use vmalloc, otherwise use kmalloc.
