[PATCH] rtl8xxxu: fix uninitialized return value in ret

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

several functions are not initializing a return status in ret
resulting in garbage to be returned instead of 0 for success.
Currently, the calls to these functions are not checking the
return, however, it seems prudent to return the correct status
in case they are to be checked at a later date.
