Display number of credits available
In debugging smb3, it is useful to display the number of credits available, so we can see when the server has not granted sufficient operations for the client to make progress, or alternatively the client has requested too many credits (as we saw in a recent bug) so we can compare with the number of credits the server thinks we have. Add a /proc/fs/cifs/DebugData line to display the client view on how many credits are available.
