cortex_m: dwt_num_comp should be set to zero in cortex_m_dwt_free()

A segmentation fault in cortex_m_endreset_event() is sometimes raised
with very broken target like Kinetis Kx with erased flash and active WDOG.
Debugging revealed that cortex_m->dwt_num_comp is 4 and
dwt_list is NULL at cortex_m:290
