drm/amd/display: Fix disbling PSR slow response issue

Browse Source 
[Why]
dmub_psr_get_state() return an invalid PSR state while disable
the PSR because convert_psr_state() doesn't recognize the state
that return from DMCUB.

[How]
Add a PSR state to make the dmub_psr_get_state() return a
correct PSR state.
