hw/nvme: fix narrowing conversion
Since nlbas is of type int, it does not work with large namespace size
values, e.g., 9 TB size of file backing namespace and 8 byte metadata
with 4096 bytes lbasz gives negative nlbas value, which is later
promoted to negative int64_t type value and results in negative
ns->moff which breaks namespace
