[Piglit] [PATCH] glx-swap-event: Fix logical-not-parentheses warning.

[Vinson Lee]

glx-swap-event.c:161:26: warning: logical not is only applied to the left hand side of this comparison [-Wlogical-not-parentheses]
                    if ( ! Intel_swap_event == 0 ) {
                         ^                  ~~
glx-swap-event.c:161:26: note: add parentheses after the '!' to evaluate the comparison first
                    if ( ! Intel_swap_event == 0 ) {
                         ^
                           (                    )
glx-swap-event.c:161:26: note: add parentheses around left hand side expression to silence this warning
                    if ( ! Intel_swap_event == 0 ) {
                         ^
                         (                 )
