The main problem for this particular use case (aside from the issue
we've already addressed) is that the passthrough device (SATA SSD) has
LBPME=0 in the READ CAPACITY(16) response. The LBP VPD is correctly
provided with LBPU flag set but because LBPME is reported as disabled we
will not attempt to issue UNMAP commands to the device.
