wifi: ath6kl: reduce WARN to dev_dbg() in callback
The warn is triggered on a known race condition, documented in the code above
the test, that is correctly handled. Using WARN() hinders automated testing.
Reducing severity.
Fixes: de2070fc4aa7 ("ath6kl: Fix kernel panic on continuous driver load/unload")
