Haoxiang Li ef4af7597f drm/vmwgfx: Fix an error return check in vmw_compat_shader_add() 
commit bf72b4b7bb upstream.

In vmw_compat_shader_add(), the return value check of vmw_shader_alloc()
is not proper. Modify the check for the return pointer 'res'.

Found by code review and compiled on ubuntu 20.04.

Fixes: 18e4a4669c ("drm/vmwgfx: Fix compat shader namespace")
