drm/msm/dpu: correct dpu_plane_virtual_atomic_check()

[ Upstream commit 1a76b255eceb9c570c6228f6393e1d63d97a22ba ]

Fix c&p error in dpu_plane_virtual_atomic_check(), compare CRTC width
too, in addition to CRTC height.

Fixes: 8c62a31607f6 ("drm/msm/dpu: allow using two SSPP blocks for a single plane")
