nvme: set the PRACT bit when using Write Zeroes with T10 PI

bugzilla: 175586 https://gitee.com/openeuler/kernel/issues/I4DVDU

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=ef799bd8ff5a8b11a3bb7767f8940a987a4415c6

--------------------------------

[ Upstream commit aaeb7bb0 ]

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.
