drm/amd/display: Add null check for head_pipe in dcn32_acquire_idle_pipe_for_head_pipe_in_layer
This commit addresses a potential null pointer dereference issue in the
dcn32_acquire_idle_pipe_for_head_pipe_in_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.
