swd: handle various failure conditions

When communication with target fails for whatever reason, it makes
sense to do JTAG-to-SWD (in case the target got power-cycled or the
DAP method was reset anyhow), SWD line reset sequence (part of
JTAG-to-SWD already) and the mandatory IDCODE read. Schedule that to
be performed on the next poll.

Fix the return values for ftdi and jlink drivers to be consistent with
OpenOCD error codes and remove ad-hoc calls to perform DAP method
switching (as it's now done from the upper layer automatically).
