  lib/util: remove try_to_free_routine()

Several memory-allocation functions in lib/util.c call
try_to_free_routine(). The routine is a function pointer. It is initialized
as do_nothing and can be set by set_try_to_free_routine(). However, no one
calls set_try_to_free_routine() in fact. So these code really do nothing.

This removes try_to_free_routine() and related lines.

This closes sheepdog/sheepdog#210.
