rt2x00: Fix race conditions in flag handling
Some of the flags should be accessed atomically to prevent race conditions. The flags that are most important are those that can change often and indicate the actual state of the device, queue or queue entry. The big flag rename was done to move all state flags to the same naming type as the other rt2x00dev flags and made sure all places where the flags were used were changed. ;) Thanks to Stephen for most of the queue flags updates, which fixes some of the most obvious consequences of the race conditions. Among those the notorious: rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 0. rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 0. rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 0.
