ath9k: fix incorrect profile type manupulation

Two MCI interrupts are generated while adding A2DP and headset profiles
with different types and same connection handle. While disconnecting,
only one MCI interrupt is generated with last added profile type value
for both profiles.

While adding second profile type decrement first one.
