Commit 9f4aa46f2a74
("block: invert the BLK_INTEGRITY{GENERATE,VERIFY} flags") caused
read_verify and write_generate to report 1 for NVMe namespaces
without PI support. This happens because BLK_INTEGRITY_NOGENERATE and
BLK_INTEGRITY_NOVERIFY were not explicitly set.
Fix this by initializing these flags by default and clearing them only
when the namespace supports PI.
