smb: smbdirect: introduce smbdirect_init_send_batch_storage()

Browse Source 
This makes it possible to use batching via public functions
without exposing the internals of struct smbdirect_send_batch.

Once the client no longer needs to use
smbdirect_connection_send_single_iter() we can remove this again.
