This removes the left over check and assignment which is no longer used
anywhere in the function and should have been removed as part of the
below mentioned patch.

Code to defer the reset(which caps the frequency of the reset) schedules the
timer and returns. Hence, following 'else-if' looks un-necessary.

The comment above should be updated too, and probably the signature of
hclge_reset_event() worth to be changed.

I can buy such explanation for the change in function signature, but have hard
time to believe that extra commit is needed to change comment above.

Yes, true. Both the comment and the prototype will be updated in near future.
I can assure you this did not go un-noticed during the change. There are
some internal subtleties which I am trying to sort out. Those might come
as part of different patch-set which deals with other related changes as well.
The current change(and some other) will pave the way for necessary refactoring
Of the code being done.

Sure, I understand your point. Earlier I thought to retain the comment for reference
and make it part of the refactor change. But will send another version changing
the comment now. No issues :)
