wifi: ath6kl: fix invalid workqueue flags in ath6kl_usb_create()

Browse Source 
ath6kl_usb_create() currently creates ath6kl_wq with flags set to 0:

  alloc_workqueue("ath6kl_wq", 0, 0)

This triggers a runtime warning in __alloc_workqueue() because the queue is
created with neither WQ_PERCPU nor WQ_UNBOUND set:

  workqueue: ath6kl_wq is using neither WQ_PERCPU or WQ_UNBOUND.
  Setting WQ_PERCPU.

Set WQ_PERCPU explicitly to match the actual execution model and remove the
warning during device probe. No functional change intended.

Fixes: 21c05ca88a ("workqueue: Add warnings and ensure one among WQ_PERCPU or WQ_UNBOUND is present")
