ceph: fix memory leaks in __ceph_sync_read()

commit d6fd6f8280f0257ba93f16900a0d3d3912f32c79 upstream.

In two `break` statements, the call to ceph_release_page_vector() was
missing, leaking the allocation from ceph_alloc_page_vector().

Instead of adding the missing ceph_release_page_vector() calls, the
Ceph maintainers preferred to transfer page ownership to the
`ceph_osd_request` by passing `own_pages=true` to
osd_req_op_extent_osd_data_pages().  This requires postponing the
ceph_osdc_put_request() call until after the block that accesses the
`pages`.
