_target_gone() and end_target() do almost same operations. We had
not unregistered pollers at the cases that sets target->is_draining
to true. The later had hit assert when the test ended with I/O error
before completion because when target->run_timer is expired,
end_target() would be called after target is freed. Hence we do
both in this patch.
Factor out the operations from _target_gone() and end_target() into
a helper function.
Then, when the target exits with error, unregister pollers of the
target immediately by replacing setting target->is_draining to true
by _end_target(target). We had seen the assert for a single case
but apply the fix for all cases.
Fixes issue #1140
