Pull up revision 1.14 (requested by tsutsui in ticket #1286):

Call zshard() twice in zshard_hb() interrupt handler for workaround
otherwise news3400 sometimes losts zs interrupts.

This should fix "serial console hiccups on sysinst" problem
reported by Mauricio <raub at kudria.com> on port-newsmips.
