wpa_cli only understands a fixed list of variables to set, and it doesn't
make sense to "undefine" them.  You can set them back to their default
values, but they must have a value.

Defaults from looking at the source:

EAPOL::heldPeriod = 60
EAPOL::startPeriod = 30
EAPOL::maxStart = 3
EAPOL::authPeriod = 30
dot11RSNAConfigPMKLifetime = 43200
dot11RSNAConfigPMKReauthThreshold = 70
dot11RSNAConfigSATimeout = 60

Running "set" from within wpa_cli should print these values, too, according
to the manpage.
