[PATCH] drm/msm: allow returning NULL from crete_address_space

[Dmitry Baryshkov]

Under some circumstances it might be required to return NULL from the
create_address_space callback, meaning that the driver should use global
address space. Use IS_ERR_OR_NULL() to guard aspace->pid assignment
instead of just IS_ERR(). This plays well with the IS_ERR_OR_NULL()
check few lines below.
