misc: Add k_panic on assert

Replaced forever loop in assert with call to a function.
In post_assert_action() function, k_panic is called.

Forever loop was preventing logs to be printed and had behavior
ependent on the context (low prioriy thread - system continue to
ork, irq - system is blocked).
