[PATCH 04/10] staging/xgifb: Fix return of uninitialized variable

[Peter Huewe <peterhuewe@gmx.de>]

Clang warning:
drivers/staging/xgifb/XGI_main_26.c: warning: variable 'ret' is
used uninitialized whenever 'if' condition:
	if (xgifb_info->mode_idx < 0) {
evaluates to true.

drivers/staging/xgifb/XGI_main_26.c:
note: uninitialized use occurs here
	return ret;

This patch initializes the variable in this case.
