s4:winbind: don't leak libnet_context into the main event context

This needs to be a talloc child of struct wbsrv_domain
otherwise the cleanup of a broken connection doesn't work.

The following command can trigger the leak on a domain controller.

root@dc:~/samba# ls -l /var/lib/samba/sysvol/samba.private/
total 16
drwxrwx---+ 5 root 3000000 4096 May 14 14:46 Policies
drwxrwx---+ 2 root 3000000 4096 May 14 11:45 scripts

gid 3000000 belongs to Builtin\Administrators.

The code triggers a ncacn_np: connection to the local smbd
and complains that domain BUILTIN is not available:

[2013/05/29 17:28:03,  2] ../source4/winbind/wb_init_domain.c:376(init_domain_recv_queryinfo)
  Expected domain name BUILTIN, DC dc.samba.private said SAMBA

In that case the connection was not closed, which is fixed by this commit.

Using ncalrpc: for all local SIDs and serving the BUILTIN domain is
a project for another day...

s3:smbd: remove code duplication in smb2_create_send()

Move the calls to smb2srv_open_recreate() from the parsing of
the create blobs (DHNC and DH2C) to a central place in the
open execution phase.
This is also where it should be called: in the durable reconnect
part, right before the call to SMB_VFS_DURABLE_RECONNECT()
