drm/amdgpu/dce11: Clean up reference counting and pinning of the cursor BOs

Take a GEM reference for and pin the new cursor BO, unpin and drop the
GEM reference for the old cursor BO in dce11 crtc_cursor_set2, and use
amdgpu_crtc->cursor_addr in dce11 set_cursor.

This fixes dce11 cursor_reset accidentally incrementing the cursor BO
pin count, and cleans up the code a little.
