Subject: [PATCH] MFV r247180: Update vendor/illumos/dist and
 vendor-sys/illumos/dist to illumos-gate 13967:92bec6d87f59

Illumos ZFS issues:
  3557 dumpvp_size is not updated correctly when a dump zvol's size is
       changed
  3558 setting the volsize on a dump device does not return back ENOSPC
  3559 setting a volsize larger than the space available sometimes succeeds
