target/arc: remove saving context during reset

Browse Source 
In arc_poll() function we handle the cases, when jtag indicates, that
processor is halted, but target->state is not TARGET_HALTED.
In case, when processor was halted and target->state was TARGET_RUNNING,
we should save context. At the same time if target->state was TARGET_RESET
we do not need to save context.

Changes: 16.04:
Fix - Move setting target->state = TARGET_HALT after
"target->state == TARGET_RUNNIG" check, otherwise
this check makes no sense
