drm/radeon: 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 radeon_crtc_cursor_set2, and use
radeon_crtc->cursor_addr in radeon_set_cursor.

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