drivers/intel/gma: Uninitialized var before if condition

The variable 'wait' is used uninitialized whenever 'if' condition is false
                    if (val & DDI_BUF_CTL_ENABLE) {
                        ^~~~~~~~~~~~~~~~~~~~~~~~

Leading to an uninitialized use occurs here:
                    if (wait)
                        ^~~~
