Currently, if hns3 PF or VF FLR reset failed after five times retry,
the reset done process will directly release the semaphore
which has already released in hclge_reset_prepare_general.
This will cause down operation fail.

So this patch fixes it by adding reset state judgement. The up operation is
only called after successful PF FLR reset.
