[ Upstream commit d9c52fd17cb483bd8a470398afcb79f86c1b77c8 ]
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.
