drm/amd/display: Fix && vs || typos 



These ANDs should be ORs or it will lead to a NULL dereference.

Fixes: fb5a3d03 ("drm/amd/display: Add NULL test for 'timing generator' in 'dcn21_set_pipe()'")
Fixes: 886571d2 ("drm/amd/display: Fix 'panel_cntl' could be null in 'dcn21_set_backlight_level()'")
