[PATCH AUTOSEL 4.4 60/63] wlcore: Fix memory leak in case wl12xx_fetch_firmware failure

[Sasha Levin]

From: Zumeng Chen <zumeng.chen@gmail.com>

[ Upstream commit ba2ffc96321c8433606ceeb85c9e722b8113e5a7 ]

Release fw_status, raw_fw_status, and tx_res_if when wl12xx_fetch_firmware
failed instead of meaningless goto out to avoid the following memory leak
reports(Only the last one listed):
