the test became nearly useless when reverting most
of its contents in commit 7d96336.
This patch adds some useful stuff back. While
we can't check that unmapped blocks are deallocated
we still can check that the blocks surrounding the
unmapped area don't get dealloaced.

We can not test that UNMAP will actually unmap anything even if
it returned status GOOD from the device.
Devices are allowed to "do nothing and return status GOOD" whenever they
want to.

Add a test for unmapping a single range of blocks and that
get_lba_status returns correct data.
Test unmapping a single block at offsets 0-255
Test unmapping 1-255 blocks at offset 0 and verify that
get_lba_status at LBA 0 returns a descriptor of 1-255 blocks.
get_lba_status at the last block of the unmapped range returns
a descriptor for a single block.
