38107d45cf Do not send SMB2 signatures for SMB3 frames
Restructure code to make SMB2 vs. SMB3 signing a protocol
specific op.  SMB3 signing (AES_CMAC) is not enabled yet,
but this restructuring at least makes sure we don't send
an smb2 signature on an smb3 signed connection. A followon
patch will add AES_CMAC and enable smb3 signing.

fec344e3f3 cifs: change cifs_call_async to use smb_rqst structs
For now, none of the callers populate rq_pages. That will be done for
writes in a later patch. While we're at it, change the prototype of
setup_async_request not to need a return pointer argument. Just
return the pointer to the mid_q_entry or an ERR_PTR.

fb308a6f22 cifs: teach signing routines how to deal with arrays of pages in a smb_rqst
Use the smb_send_rqst helper function to kmap each page in the array
and update the hash for that chunk.

3c1bf7e48e CIFS: Enable signing in SMB2
Use hmac-sha256 and rather than hmac-md5 that is used for CIFS/SMB.

Signature field in SMB2 header is 16 bytes instead of 8 bytes.

Automatically enable signing by client when requested by the server
when signing ability is available to the client.
