Since commit 8437754c8335 ("ath6kl: Use vmalloc instead of kmalloc for
fw") 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.
