[Intel-xe] [PATCH v2 03/10] drm/xe: Fix checking for unset value

[Lucas De Marchi]

Commit 0f885eced0a8 ("drm/xe: NULL binding implementation") introduced
the NULL binding implementation, but left a case in which the out value
is_vram is not set and the caller will use whatever was on stack.
Eventually the is_vram out could be removed, but this should at least
fix the current bug.
