6.6-stable review patch. If anyone has any objections, please let me know.

From: Stefan Metzmacher metze@samba.org
[ Upstream commit 1cde0a74a7a8951b3097417847a458e557be0b5b ]
If we are using a hardcoded delay of 0 there's no point in using delayed_work it only adds confusion.
The client also uses a normal work_struct and now it is easier to move it to the common smbdirect_socket.
