nvme: set the PRACT bit when using Write Zeroes with T10 PI
[ Upstream commit aaeb7bb061be545251606f4d9c82d710ca2a7c8e ]
When using Write Zeroes on a namespace that has protection
information enabled they behavior without the PRACT bit
counter-intuitive and will generally lead to validation failures
when reading the written blocks. Fix this by always setting the
PRACT bit that generates matching PI data on the fly.
