Ilya Dryomov fc218544fb ceph: fix iov_iter issues in ceph_direct_read_write() 
dio_get_pagev_size() and dio_get_pages_alloc() introduced in commit
b5b98989dc ("ceph: combine as many iovec as possile into one OSD
request") assume that the passed iov_iter is ITER_IOVEC.  This isn't
the case with splice where it ends up poking into the guts of ITER_BVEC
or ITER_PIPE iterators, causing lockups and crashes easily reproduced
with generic/095.

Rather than trying to figure out gap alignment and stuff pages into
a page vector, add a helper for going from iov_iter to a bio_vec array
and make use of the new CEPH_OSD_DATA_TYPE_BVECS code.

Fixes: b5b98989dc ("ceph: combine as many iovec as possile into one OSD request")
