Currently sme_ft_send_update_key_ind() takes a tHalHandle context
param. However this is a static internal function, and hence it
should be using the "real" context pointer type tpAniSirGlobal instead
of the opaque reference tHalHandle, so update the API to expect
tpAniSirGlobal (which is what is already being passed by
sme_ft_update_key()).
