drm/xe/eustall: Store forcewake reference in stream structure

Calls to xe_force_wake_put() should generally pass the exact reference
returned by xe_force_wake_get().  Since EU stall grabs and releases
forcewake in different functions, xe_eu_stall_disable_locked() is
currently calling put with a hardcoded RENDER domain.  Although this
works for now, it's somewhat fragile in case the power domain(s)
required by stall sampling change in the future, or if workarounds show
up that require us to obtain additional domains.

Stash the original reference obtained during stream enable inside the
stream structure so that we can use it directly when the stream is
disabled.
