slim_ngd: Handle error flags before handling SENT flag

It's possible that error flags were set alongwith SENT flag for
TX transaction status. In such a scenario, error flag status should
be handled (and SENT flag should be cleared). Move error-flag
handling ahead of SENT flag handling to avoid interrupt being called
twice, and completion being set twice.

Slim_ngd: Modify waiting mechanism in kthread

wait_for_completion_timeout() is not a good option in
kthread as it leads to scheduling the kthread on the every timeout.
Hence modify it to wait_for_completion() from
wait_for_completion_timeout().
