[PATCH] lib: fwts_args: fix arg parameter sanity range checking

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

An earlier commit remove the arg parameter sanity range checking
which should be re-instated. Add the code back.

Fixes: 973a296cad30 ("v2 - lib: fwts_args: handle cases to set optarg_handler for long options.")
