cifs: Remove unused functions
cifs_ses_find_chan() has been unused since commitf486ef8e20
("cifs: use the chans_need_reconnect bitmap for reconnect status") cifs_read_page_from_socket() has been unused since commitd08089f649
("cifs: Change the I/O paths to use an iterator rather than a page list") cifs_chan_in_reconnect() has been unused since commitbc962159e8
("cifs: avoid race conditions with parallel reconnects") Remove them. Signed-off-by: Dr. David Alan Gilbert <linux@treblig.org> Signed-off-by: Steve French <stfrench@microsoft.com>
