Addresses a race condition which could cause the RM to overcommiting LMs to DP when multiple DP displays are used. sde_rm_get_resource_info now uses the RM's mutex and assumes a null encoder is not a built in display so that it can return an accurate count of unreserved resources. DP layer now maintains internal accounting of LMs in use to avoid validating modes that have insufficient remaining resources.
