[PATCH] regulatory: don't rule out some valid rules

[Eliad Peller <eliad@wizery.com>]

commit 6d87df6 ("regdb: allow 40 MHz on world roaming
channels 12/13") in wireless-regdb did the following
change:

-        # Channel 12 - 13. No HT40 channel fits here
-        (2457 - 2482 @ 20), (3, 20), PASSIVE-SCAN, NO-IBSS
+        # Channel 12 - 13.
+        (2457 - 2482 @ 40), (3, 20), PASSIVE-SCAN, NO-IBSS

in order to allow HT40+ on lower channels (such as 9).

However, the current regulatory rules verification forbids
such rules, as 2482 - 2457 < 40.
Remove this requirement from the rules verification function.
