firmware loader: fix another compile warning with PM_SLEEP unset
This patch fixes another compiling warning with PM_SLEEP unset:
drivers/base/firmware_class.c:221:29: warning: 'fw_lookup_buf' defined
but not used [-Wunused-function]
This time I do build kernel with both PM_SLEEP set and unset, and no
warning found any more with the patch.
