scsi: core: Use blist_flags_t consistently

Use the type blist_flags_t for all variables that represent blacklist
flags. Additionally, suppress recently introduced sparse warnings
related to blacklist flags.

[mkp: fixed commit id]

Fixes: 5ebde469 ("scsi: Use 'blist_flags_t' for scsi_devinfo flags")
