drm/amd/display: Guard against null stream dereference in do flip
[Why]
During suspend under some hardware configurations can result in a
series of atomic commits with a NULL stream status - which
causes a NULL pointer dereference. This should be guarded.
[How]
Exit early from the function - if we can't access the stream then
there isn't anything that can be done here.
