ha: Perform child rekeying outside of CHILD_SA enumerator

When rekey_child_sa is called while enumerating the children of an IKE_SA, and
the child to be rekeyed is redundant a QUICK_DELETE task is queued instead of a
QUICK_MODE task. This alters the IKE_SA's list of children (ike_sa_t::child_sas)
invalidating the current element of the child_sa_enumerator. The enumerate
function of linked_list_t will then advance to an element with unpredictable
contents most likely resulting in an segmentation violation. A similar behavior
should be observed when delete_child_sa is called.

This patch creates a list of protocol/spi values while holding the
child_sa_enumerator and performs the rekeying (deletion of redundant) chlidren
after releasing the enumerator.
