drm/msm/dpu: Fix error pointers in dpu_plane_virtual_atomic_check

In the Linux kernel, the following vulnerability has been resolved:

drm/msm/dpu: Fix error pointers in dpu_plane_virtual_atomic_check

The function dpu_plane_virtual_atomic_check was dereferencing pointers
returned by drm_atomic_get_plane_state without checking for errors. This
could lead to undefined behavior if the function returns an error pointer.

This commit adds checks using IS_ERR to ensure that plane_state is
valid before dereferencing them.
