test_inquiry_block_limits: Only query VPD page B2h if LBPME = 1

Browse Source 
In the READ CAPACITY response support for logical block provisioning
is indicated via the LBPME (logical block provisioning management
enabled) bit. Since the logical block provisioning VPD page (B2h)
is optional, only query it if LBPME = 1.
