[PATCH 5.15 124/132] net: atlantic: reduce scope of is_rsc_complete

From: Grant Grundler <grundler@chromium.org>

[ Upstream commit 79784d77ebbd3ec516b7a5ce555d979fb7946202 ]

Don't defer handling the err case outside the loop. That's pointless.

And since is_rsc_complete is only used inside this loop, declare
it inside the loop to reduce it's scope.
