firmware: turris-mox-rwtm: fix reply status decoding function
[ Upstream commit
e34e60253d9272311831daed8a2d967cf80ca3dc ]
The status decoding function mox_get_status() currently contains an
incorrect check: if the error status is not MBOX_STS_SUCCESS, it always
returns -EIO, so the comparison to MBOX_STS_FAIL is never executed and
we don't get the actual error code sent by the firmware.
Fix this.
