bhyve: validate the NVMe LBA start and count

Add checks that the combination of Starting LBA and Number of Logical
Blocks in a command will not exceed the range of the underlying storage.

Note that because NVMe specifices the Starting LBA as a uint64_t, care
must be taken when converting it and the block count to avoid an integer
overflow.

Fixes UNH Tests 2.2.3, 2.3.2, and 2.4.2
