Kernel/Sessions: Wake up any threads waiting on a ServerSession when its client is closed
The error code 0xC920181A will be returned by svcReplyAndReceive when the wakeup callback runs. This lets LLE services be properly notified of clients closing the connection so they can end their handler threads instead of letting them linger indefinitely, taking up connection slots in their parent port.
