Tx99 is typically configured via a monitor mode interface, which does not get added to the driver as a vif. Since the code currently expects a configured virtual interface for tx99, enabling tx99 via debugfs fails. Since the vif is not needed anyway, remove all checks for it.

Obviously this should be CONFIG_ATH9K_TX99, I'll fix that in the pending branch. -- Kalle Valo
