task #29600094

commit da90921acc62c71d27729ae211ccfda5370bf75b upstream.
Backport summary: for 4.19 kernel ICX PCIe Gen4 support.

The code sets IRQS_REPLAY unconditionally whether the resend happens or
not. That doesn't have bad side effects right now, but inconsistent state
is always a latent source of problems.
