drm/amd/display: Add null check for headpipe in dcn201acquirefreepipeforlayer

This commit addresses a potential null pointer dereference issue in the dcn201_acquire_free_pipe_for_layer function. The issue could occur when head_pipe is null.

The fix adds a check to ensure head_pipe is not null before asserting it. If head_pipe is null, the function returns NULL to prevent a potential null pointer dereference.

Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/resource/dcn201/dcn201resource.c:1016 dcn201acquirefreepipeforlayer() error: we previously assumed 'head_pipe' could be null (see line 1010)
