cortex_m_poll_one() detects reset testing S_RESET_ST sticky bit. If the signal comes unexpectedly, poll must return TARGET_RESET state. On the contrary in case of polling inside of an OpenOCD reset command, TARGET_RESET has been has already been set and we need to get out of it as quickly as possible. The original code needs 2 polls: the first clears S_RESET_ST and keeps TARGET_RESET state, the current TARGET_RUNNING or TARGET_HALTED is reflected as late as the second poll is done. Change the logic to keep in TARGET_RESET only when necessary.
