Fixes build break w/ latest xserver:

drmmode_display.c: In function 'drmmode_reallocate_scanout':
drmmode_display.c:1149:4: error: passing argument 1 of 'pScrn->EnableDisableFBAccess' makes pointer from integer without a cast [-Werror]
drmmode_display.c:1149:4: note: expected 'ScrnInfoPtr' but argument is of type 'int'
drmmode_display.c:1183:4: error: passing argument 1 of 'pScrn->EnableDisableFBAccess' makes pointer from integer without a cast [-Werror]
drmmode_display.c:1183:4: note: expected 'ScrnInfoPtr' but argument is of type 'int'
