Add support for device surprise removal and other PCI errors.

• When device disappears from PCI indicate error device state and:
  1. Trigger command completion for all pending commands
  2. Prevent new commands from executing and return:
     • success for modify and remove/cleanup commands
     • failure for create/query commands
  3. When reclaiming pages for a device in error state don't ask FW to return all given pages, just release the allocated memory
