    rt2x00: do not increment sequence number while re-transmitting · 746ba11f

    Currently rt2x00 devices retransmit the management frames with
    incremented sequence number if hardware is assigning the sequence.
    
    This is HW bug fixed already for non-QOS data frames, but it should
    be fixed for management frames except beacon.
    
    Without fix retransmitted frames have wrong SN:
    
     AlphaNet_e8:fb:36 Vivotek_52:31:51 Authentication, SN=1648, FN=0, Flags=........C Frame is not being retransmitted 1648 1
     AlphaNet_e8:fb:36 Vivotek_52:31:51 Authentication, SN=1649, FN=0, Flags=....R...C Frame is being retransmitted 1649 1
     AlphaNet_e8:fb:36 Vivotek_52:31:51 Authentication, SN=1650, FN=0, Flags=....R...C Frame is being retransmitted 1650 1
    
    With the fix SN stays correctly the same:
    
     88:6a:e3:e8:f9:a2 8c:f5:a3:88:76:87 Authentication, SN=1450, FN=0, Flags=........C
     88:6a:e3:e8:f9:a2 8c:f5:a3:88:76:87 Authentication, SN=1450, FN=0, Flags=....R...C
     88:6a:e3:e8:f9:a2 8c:f5:a3:88:76:87 Authentication, SN=1450, FN=0, Flags=....R...C
