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()
