drm/amd/display: Clean up PSR helper functions

Browse Source 
[Why & How]
Use the existing local dc variable in amdgpu_dm_set_psr_caps() instead
of redundantly dereferencing link->ctx->dc.

Simplify amdgpu_dm_psr_is_active_allowed() by replacing with early
return and inlining the intermediate stream variable.

No functional changes.
