Subject: rt2x00: Fix PCI interrupt processing race on SMP systems

When toggle_irq is called for PCI devices to disable device interrupts
it used tasklet_disable to wait for a possibly running tasklet to finish.
However, on SMP systems the tasklet might still be scheduled on another CPU.
Instead, use tasklet_kill to ensure that all scheduled tasklets are finished
before returning from toggle_irq.

Furthermore, it was possible that a tasklet reenabled its interrupt even
though interrupts have been disabled already. Fix this by checking the
DEVICE_STATE_ENABLED_RADIO flag before reenabling single interrupts
during tasklet processing.

While at it also enable/kill the TBTT and PRETBTT tasklets in the
toggle_irq callback and only use tasklet_kill in stop_queue to wait
for a currently scheduled beacon update before returning.

Subject: mac80211: add ieee80211_vif param to tsf functions

TSF can be kept per vif.
Add ieee80211_vif param to set/get/reset_tsf, and move
the debugfs entries to the per-vif directory.

Update all the drivers that implement these callbacks.

Subject: mac80211: pass vif param to conf_tx() callback

tx params should be configured per interface.
add ieee80211_vif param to the conf_tx callback,
and change all the drivers that use this callback.

The following spatch was used:
@rule1@
struct ieee80211_ops ops;
identifier conf_tx_op;
@@
	ops.conf_tx = conf_tx_op;

@rule2@
identifier rule1.conf_tx_op;
identifier hw, queue, params;

		u16 queue,
		const struct ieee80211_tx_queue_params *params) {...}
