An out-of-bounds read on array ath10k_rates is occurring because
the maximum number of elements is currently based on the size of
the array and not the number of elements in the array. Fix this
by using ARRAY_SIZE instead of sizeof.
Detected by CoverityScan, CID#1473918 ("Out-of-bounds read")
Fixes: f279294e9ee2 ("ath10k: add support for configuring management packet rate")
