Subject: [PATCH 5.4 235/453] Bluetooth: btusb: Add the missed release_firmware() in btusb_mtk_setup_firmware()

From: Jing Xiangfeng <jingxiangfeng@...wei.com>

[ Upstream commit d1e9d232e1e60fa63df1b836ec3ecba5abd3fa9d ]

btusb_mtk_setup_firmware() misses to call release_firmware() in an error
path. Jump to err_release_fw to fix it.
