cifs_iovec_read: keep iov_iter between the calls of cifs_readdata_to_iov()
... we are doing them on adjacent parts of file, so what happens is that
each subsequent call works to rebuild the iov_iter to exact state it
had been abandoned in by previous one. Just keep it through the entire
cifs_iovec_read(). And use copy_page_to_iter() instead of doing
kmap/copy_to_user/kunmap manually...
