drm/vmwgfx: NULL pointer dereference in vmw_surface_define_ioctl()
commit 36274ab8c596f1240c606bb514da329add2a1bcd upstream.
Before memory allocations vmw_surface_define_ioctl() checks the
upper-bounds of a user-supplied size, but does not check if the
supplied size is 0.
Add check to avoid NULL pointer dereferences.
