lib/kmod: Fix error reporting for kmod load/unload

A "return -err ? err < 0 : err" managed to slip through. So if err was
set, we returned 0 or 1 based on sign, or 0 if err was zero.

If err is negative, we want treat it as an error, so report it back
to the caller, all other values were a success, so convert those to 0.

This should actually be no functional change, as all errors were
reported as 1, and everything else as 0.
