octeontx2-af: fix order of queue work and interrupt disable

commit edeb9bc6470d0323e8f2b9716d2f3caf77637ffc from
git@git.assembla.com:cavium/WindRiver.linux.git

Clear and disable interrupt before queueing work as there might be
a chance that work gets completed on other core faster and
interrupt enable as a part of the work completes before
interrupt disable in the interrupt context. This leads to
permanent disable of interrupt.
