Subject: [wireless] mac80211: fix reported wireless extensions version

O-Subject: [PATCH RHEL5.5] mac80211: claim wireless extensions version 20
	instead of 21
Bugzilla: 513430

The mac80211 component in rhel5 postdates the wireless extensions code
there.  Consequently, the backport claims a later we_version_source
value.  This is actually a long-lived oversight and WE20 is actually
implemented, but the mismatch causes the wireless_tools component
to spit-out a scary warning when those tools (iwconfig, iwlist,
etc) are run.  This patch bumps the claimed version downward to
match what the kernel's WIRELESS_EXT definition says (and what the
wireless_tools expect).

Fixes bugzilla #513430
