Subject: [PATCH] staging: r8188eu: os_dep: remove the goto statement

Remove the goto statement from rtw_init_drv_sw(). In this function goto
can be replace by return statement. As on goto label exit, function
only return it is not performing any cleanup. Avoiding goto will
improve the function readability.
