test_firmware: fix error return getting clobbered
In the case where eq->fw->size > PAGE_SIZE the error return rc is being set to EINVAL however this is being overwritten to rc = req->fw->size because the error exit path via label 'out' is not being taken. Fix this by adding the jump to the error exit path 'out'. Detected by CoverityScan, CID#1453465 ("Unused value") Fixes: c92316bf8e94 ("test_firmware: add batched firmware tests") Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
