Andrey V. Elsukov 068273571b Update ifr_name before invoking IPSECSREQID ioctl, this fixes the case,
when `ifconfig ipsec create reqid N` command invoked without interface
unit number. The "name" global variable is updated after interface
cloning in the ifclonecreate() and contains actual interface name.
