Bug#656813: [PATCH 2/2] ipw2100: Fix order of device registration

[Ben Hutchings <ben@decadent.org.uk>]

Currently cfg80211 fails to create a "phy80211" symlink in sysfs from
the net device to the wiphy device.  The latter needs to be registered
first.

Compile-tested only.

This appears to have the same bug as ipw2200.
