usr.sbin/ndp: Cleanup in preparation to add libxo support
* Constify rtpref_str declaration * Remove unused h_errno declaration * Use time_t type for expire * Use strlcpy to set static "?" value to ifname * Rename local variable 's' to stop shadowing global definition * Close socket used in pfx_flush() * Use local variables for sock() in setdefif() and getdefif() * Increase WARNS to 3 Reviewed by: allanjude, kevans Approved by: allanjude Sponsored by: Rubicon Communications, LLC (Netgate) Differential Revision: https://reviews.freebsd.org/D11118
