Subject: [PATCH] sched/misc/assert.c: don't compile dump_assert_info logic if
 CONFIG_DEBUG_ALERT=n

Don't compile dump_assert_info logic if CONFIG_DEBUG_ALERT=n

With _alert() disabled this logic does nothing, but the compiler
is not smart enough to optimize this code.

on minimal stm32f3 configuration it saves 220B of flash.
