Subject: [PATCH v2 08/15] net: wireless: simplify return flow for usb_control_msg

remove int ret suggested by Jiri Slaby
This patch is to the at76c50x-usb.c file that fixes up warning
reported by coccicheck:

WARNING: end returns can be simplified if negative or 0 value

Prefer direct return value instead of writing 2-3 more sentence.
