kvm_geterr: handle `kd` == NULL in a deterministic/graceful manner

Return a NUL string instead of just working by accident with kvm_geterr(3)
when MALLOC_PRODUCTION is disabled (I didn't confirm the MALLOC_PRODUCTION
being enabled path).

Document the new explicit return behavior for kvm_geterr(3), as well
as the previous implicit behavior, i.e., the buffer attached to
returned via kvm_geterr(3) would be empty if a previous error hadn't been
stored in `kd`.

r315688:

kvm_write: fix -Wcast-qual warning in pointer arithmetic argument

Cast buf to `const char *` when doing arithmetic operation to match
`cp`'s type [1].
