iwlwifi: Fix double-free problems in iwl_req_fw_callback() [ Upstream commit a8627176b0de7ba3f4524f641ddff4abf23ae4e4 ] In the error handling code of iwl_req_fw_callback(), iwl_dealloc_ucode() is called to free data. In iwl_drv_stop(), iwl_dealloc_ucode() is called again, which can cause double-free problems. To fix this bug, the call to iwl_dealloc_ucode() in iwl_req_fw_callback() is deleted. This bug is found by a runtime fuzzing tool named FIZZER written by us.
