iscsi-target: Convert chap_server_compute_md5 to use kstrtoul

This patch converts chap_server_compute_md5() from simple_strtoul() to
kstrtoul usage().

This addresses the case where a empty 'CHAP_I=' key value received during
mutual authentication would be converted to a '0' by simple_strtoul(),
instead of failing the login attempt.
