kmsdrm: fix gbm surface dimensions not matching the mode being set

Browse Source 
commit 2067a7db8e introduced new surface_w and surface_h
variables which were passed to gbm_surface_create rather than the dimensions from the
drmModeModeInfo structure. commit 5105ecf8b1 further
refactored this code and no longer synchronized these variables inside
KMSDRM_SetDisplayMode, breaking it

this change removes the variables since they're seemingly redundant to begin with
