wl-drm: Properly retrieve output geometry and propertly set output mode
wl-drm: Properly retrieve output geometry and propertly set output mode

Previously when we were getting the output size, the resulting
geometry was being placed in the wrong variables which resulting in
randr screen config modes being set to zero. This patch also fixes the
issue where when setting drm2 output mode, we were always passing in
0x0 as the output geometry.

@fix
