fairland: Drop "might be too small to fit continents" warning

Commit de81e4e20 "Change fairland not to reject small worlds without
trying" (v4.3.25) downgraded it from error to warning, pointing out it
the size may well work, and when it doesn't, fairland fails cleanly.

When it works, the warning is pointless.  When it doesn't, it's
redundant.  Drop it.
