Do not drop connection attempt when reconnecting to the same ESS

Browse source 
Connection attempt could have been intermittently drop when reconnecting
to the same ESS due the current BSS entry getting removed immediately
after the disconnection for the purpose of reconnecting to the same ESS.

Avoid this by not removing a BSS entry for the same ESS when in this
special state of trying to reconnect to the same ESS.
