netfs, cifs: Improve some debugging bits

Browse Source 
Improve some debugging bits:

 (1) The netfslib _debug() macro doesn't need a newline in its format
     string.

 (2) Display the request debug ID and subrequest index in messages emitted
     in smb2_adjust_credits() to make it easier to reference in traces.
