[PATCH AUTOSEL 6.11 193/244] drm/amd/display: Check stream_status before it is used

[Sasha Levin]

From: Alex Hung <alex.hung at amd.com>

[ Upstream commit 58a8ee96f84d2c21abb85ad8c22d2bbdf59bd7a9 ]

[WHAT & HOW]
dc_state_get_stream_status can return null, and therefore null must be
checked before stream_status is used.

This fixes 1 NULL_RETURNS issue reported by Coverity.
