route/link: fix dangling pointer after rtnl_link_get_ifalias(link, NULL)

Fixed bug that left a dangling pointer after clearing the ifalias
property. This happened when calling 'rtnl_link_get_ifalias(link, NULL)'
on a link that has already an ifalias set.

This can cause a crash and/or a double-free.

Error found by coverity.
