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. Signed-off-by: Sage Weil <sage@newdream.net>
