ath5k: fix ah_txq_isr_txok_all setting

Browse Source 
The struct ath5k_hw member ah_txq_isr_txok_all is never reset/assigned
outside of ath5k_hw_get_isr() and with the used bitwise-or in the
interrupt handling accumulates all ever set interrupt flags.

Fix this by clearing ah_txq_isr_txok_all before assigning.

Patch tested with Senao NMP-8602 card

  Qualcomm Atheros AR5413/AR5414 Wireless Network Adapter [AR5006X(S) 802.11abg] (rev 01)
  ath5k: phy6: Atheros AR5413 chip found (MAC: 0xa4, PHY: 0x61)

running IBSS mode against Atheros (ath9k) card using
ping and iperf traffic.
