Ronnie Sahlberg 64f23e5430 cifs: destage dirty pages before re-reading them for cache=none 
commit bb44c31cdcac107344dd2fcc3bd0504a53575c51 upstream.

This is the opposite case of kernel bugzilla 216301.
If we mmap a file using cache=none and then proceed to update the mmapped
area these updates are not reflected in a later pread() of that part of the
file.
To fix this we must first destage any dirty pages in the range before
we allow the pread() to proceed.
