drm/msm: fix return value check in _msm_gem_kernel_new()
In case of error, the function msm_gem_get_vaddr() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().
Fixes: 8223286d62e2 ("drm/msm: Add a helper function for in-kernel
buffer allocations")
