[PATCH] prism54: correct assignment of DOT1XENABLE in WE-19 codepaths

Correct assignment of DOT1XENABLE in WE-19 codepaths.
RX_UNENCRYPTED_EAPOL = 1 really means setting DOT1XENABLE _off_, and
vice versa.  The original WE-19 patch erroneously reversed that.  This
patch fixes association with unencrypted and WEP networks when using
wpa_supplicant.

It also adds two missing break statements that, left out, could result
in incorrect card configuration.
