[PATCH 0/3] Fixes for gapped scatters

[Sagi Grimberg]

This small set addresses some issues with gapped scattered IOs. The
motivation of this is to have the iser driver take advantage of it too.

Patch 1 prevent gapped SG_IO if the driver can't handle gaps.
Patches 2,3 prevent gapped integrity payloads (for drivers that
support data integrity).

Review is welcome.

  block: Refuse request/bio merges with gaps in the integrity payload
  block: Refuse adding appending a gapped integrity page to a bio
