cifs: Remove unused functions

Browse Source 
cifs_ses_find_chan() has been unused since commit
f486ef8e20 ("cifs: use the chans_need_reconnect bitmap for reconnect status")

cifs_read_page_from_socket() has been unused since commit
d08089f649 ("cifs: Change the I/O paths to use an iterator rather than a page list")

cifs_chan_in_reconnect() has been unused since commit
bc962159e8 ("cifs: avoid race conditions with parallel reconnects")

Remove them.
