From: Johan Hedberg <johan.hedberg@xxxxxxxxx> When we're in the process of receiving keys in phase 3 of SMP we keep track of which keys are still expected in the smp->remote_key_dist variable. If we still have some key bits set we need to continue waiting for more PDUs and not needlessly call smp_distribute_keys(). This patch fixes two such cases in the smp_cmd_master_ident() and smp_cmd_ident_addr_info() handler functions.
