linux-yocto/3.14/3.17: allmodconfig/allyesconfig build fixes

It was found that some of the recent feature merges for 3.14/3.17 are
not allmodconfig and allyesconfig safe.

Since this is a basic test before kernel patches are submitted, we've
fixed the features to meet this standard.

Integrating the following fixes from Paul Gortmaker:

  b4213d81ea3f fat: don't use obsolete random32 call in namei_vfat
  2cc7eba15c1f cryptodev: stomp dynamic version numbering for in tree builds
  5d1dda7aae4b Target/dif: Introduce protection-passthough-only mode
  3d9772d8facf vhost: fix compile fail due to reallocated acked_features field.
  efad59d3a174 virtio-scsi.h: Add virtio_scsi_cmd_req_pi + VIRTIO_SCSI_F_T10_PI bits
  902f34d36102 aufs: apply aufs3-mmap.patch from 3.14 branch
  30efc2e9484e aufs: import core files from aufs3.14 20140915
  e42f87adef10 Revert "aufs: aufs3-mmap.patch"
