rt2x00: Only set the TBCN flag when the interface is configured to send beacons.

These flags used to be fixed to one in rt2500pci_config_type, which
caused the beacon timer interrupt to fire. This would lead to
rt2x00lib_beacondone adding work which called
rt2x00lib_beacondone_scheduled which called ieee80211_beacon_get which
printed an error about not having any beacon data.

With this patch, these interrupts are only generated when the interface
is configured to send beacons.
