TESTS: Keep the LogicalBlockProvisioning VPD around after we read it during
test startup.
TESTS: Make READCAPACITY16PI test more verbose under -V
TESTS: Relax the tests for BlockLimit VPD page length.
Discussions on linux-scsi indicate that some SBC-2 devices may provide
some SBC-3 features and thus a SBC-3 BlockLimit page.

Supporting more than you claim is a transgression but a relatively minor
one, so lets turn a blind eye to it.
Supporting less than you claim is a serious transgression and will always
result in a harsh test failure.
TESTS: BlockLimits VPD. If a device returns a SBC-3 VPD (page length 0x3c)
but does not claim SBC-3 support then print a harsh warning
about this.
