[PATCH] zd1211rw: Allow channels 1-11 for unrecognised regulatory domains
Zen Kato's device has a regulatory domain value of 0x49, which is not an
IEEE 802.11 code and is not even identified in the vendor driver.
Recent versions of the vendor driver don't even look at the regdomain
value any more, and just allow channels 1-11 everywhere. This patch
brings us more in line with that behaviour, by allowing channels 1-11
for regdomains which we don't know about.
