[PATCH 1/4] ceph: kill ceph_osdc_writepages() "nofail" parameter

[Alex Elder <elder@inktank.com>]

There is only one caller of ceph_osdc_writepages(), and it always
passes the value true as its "nofail" argument.  Get rid of that
argument and replace its use in ceph_osdc_writepages() with the
constant value true.

This and a number of cleanup patches that follow resolve:
