[PATCH] ieee80211: Capability field is called ESS, not BSS

IEEE 802.11 has a capability field flag called ESS, but ieee80211 had
renamed this to BSS for some reason. hostap has been using
WLAN_CAPABILITY_ESS and since that matches with the standard, lets use
it as the name for this define. Add WLAN_CAPABILITY_BSS as a backwards
compatibility name for the same bit since ieee80211 and ipw2200 are
using this and there are versions outside kernel tree that expect to
find this define name.
