svn commit: r324634 - head/sys/dev/nvme

[Warner Losh]

Author: imp
Date: Sun Oct 15 16:19:09 2017
New Revision: 324634
URL: https://svnweb.freebsd.org/changeset/base/324634

Log:
  Use nvme_ctrlr_poll instead of nvme_ctrlr_intx_handler since it is
  more general and doesn't try to access registers that may be undefined
  when the card is in MSIX mode.
  
  This change, along with r324630, r324631, r324632, makes nda crash
  dumps work again. Previously, they only worked on CPU 0 when the stack
  garbage was just so.
