Hi!
These are few assorted fixes and features for the userspace
nvme driver.

Tested that on my laptop with my Samsung X5 thunderbolt drive, which
happens to have 4K sectors, support for discard and write zeros.

Also bunch of fixes sitting in my queue from the period when I developed
the nvme-mdev driver.

Best regards,
	Maxim Levitsky

  block/nvme: don't flip CQ phase bits
  block/nvme: fix doorbell stride
  block/nvme: support larger that 512 bytes sector devices
  block/nvme: add support for write zeros
  block/nvme: add support for discard
