target/cortex_a: fix waiting for target halted after step

Depending on adapter speed, the function cortex_a_poll() can take
time to execute and can complete successfully when the timeout is
already expired. Checking the timeout at function return causes a
timeout error while that could be avoided.

Check the target status at cortex_a_poll() return, before checking
for the timeout.
