[PATCH 5/5] Bluetooth: btmrvl: Use common error handling code in btmrvl_sdio_download_fw_w_helper()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Mon, 12 Mar 2018 11:30:28 +0100

Add a jump target so that the setting of a specific error code is stored
only once at the end of this function.
