[PATCH 3/7] nouveau/gsp: cleanup IS_ERR_OR_NULL in rpc_rd

[Hongling Zeng]

The underlying nvkm_gsp_rpc_get() function returns error pointers,
not NULL. This is now documented in the function's kernel-doc comment
(added in previous patch).
Therefore, checking for NULL with IS_ERR_OR_NULL() is redundant and
IS_ERR() is sufficient.

This affects nvkm_gsp_rpc_rd().
