LDAP: avoid complex realloc logic in save_rfc2307bis_group_memberships
https://fedorahosted.org/sssd/ticket/1761
The function tried to be smart and realloc only when needed, but that
only lead to hard-to find bugs where the logic would not allocate the
proper space. Remove the reallocation and prefer readability over speed
in this case.
