Subject: [PATCH] ceph: don't use writeback_control in writepages completion

The ->writepages writeback_control is not still valid in the writepages
completion.  We were touching it solely to adjust pages_skipped when there
was a writeback error (EIO, ENOSPC, EPERM due to bad osd credentials),
causing an oops in the writeback code shortly thereafter.  Updating
pages_skipped on error isn't correct anyway, so let's just rip out this
(clearly broken) code to pass the wbc to the completion.
