Leah Rowe 978c30a961 util/nvmutil: safer SSIZE_MAX define ...

the current one assumes two's compliment and no
padding bits. i assert two's compliment earlier
in code, but it doesn't guarantee:

sizeof(ssize_t) == sizeof(size_t)

it's theoretically possible that size_t=64
and ssize_t=32, and then the macro would break.

this new version uses SIZE_MAX instead, without
subtraction, but halves it using a bit shift.

this may still break, but it should work nicely.
