cortex_m: fix bug in poll() machine state (external resume awareness)

This patch covers the fact that cortex_m could be resumed externally by
Cross Trigger Interface or by direct write to DHSCR ...

To reproduce:
 - halt the target
 - then run the core through DHCSR (mww 0xe000edf0 0xa05f0001)
 => this resumes the core, but target state in OpenOCD remains HALTED.
