Subject: Drop now-trivial `decayed_offset_msat` helper utility
X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=7e11121d61545616eb27bb657a4c76295e9c7ee6;p=rust-lightning

Drop now-trivial `decayed_offset_msat` helper utility

As we now no longer decay bounds information when fetching them,
there is no need to have a decaying-fetching helper utility.
