When a WCID was already assigned to a STA the key configuration
functions need to use the same WCID for configuring the keys. Hence, add
the WCID to the crypo configuration structure.

This implements a basic sta_add and sta_remove callback. Introduce a new
structure rt2x00_sta and ask mac80211 to allocate it as private part of
its ieee80211_sta. rt2x00_sta only contains the WCID for now.
The sta_add callback allows the driver to assign a WCID to a station
that is currently being added. The same wcid is also passed to the
sta_remove callback one mac80211 removes this STA.

rt2800 devices are not capable of configuring arbitrary LED on/off

used by the hw when the LED mode is set to "blink upon TX".
Hence, remove the blink callback. This will result in software emulation
for LED blinking.

The latter was the only place that called the first. The two
functions were split when the iwl_pci_probe called iwl_pci_down
upon failure in the probe. Since iwl_pci_probe undoes its work by
itself, there is no need to split between iwl_pci_down, and
iwl_pci_remove.

The firmware only asks for one dummy packet at a time, but sometimes we
