[PATCH v3 2/2] block: Correctly initialize BLK_INTEGRITY_NOGENERATE and BLK_INTEGRITY_NOVERIFY

Currently, BLK_INTEGRITY_NOGENERATE and BLK_INTEGRITY_NOVERIFY are not
explicitly set during integrity initialization. This can lead to
incorrect reporting of read_verify and write_generate sysfs values,
particularly when a device does not support integrity. Ensure that these
flags are correctly initialized by default.
