Fix bug #7791 - gvfsd-smb (Gnome vfs) fails to copy files from a SMB share using SMB signing.

The underlying problem is that the old code invoked by cli_write() increments
cli->mid directly when issuing outstanding writes. This should now be done only
in libsmb/clientgen.c to make metze's new signing engine works correctly. Just
deleting this code fixes the problem.
