rt2x00: rt2800usb: fix status register reread logic
Another good catch from Jakub Kicinski. This patch fixes my recent commit: ed61e2b02027935520d1be884fac0b2ffce8379a "rt2x00: rt2800usb: rework txdone code" We should reread status register only when nobody else start already reading status i.e. test_and_set_bit(TX_STATUS_READING, flags) return 0.
