dpaa2-eth: prevent array underflow in update_cls_rule()
The "location" is controlled by the user via the ethtool_set_rxnfc()
function. This update_cls_rule() function checks for array overflows
but it doesn't check if the value is negative. I have changed the type
to unsigned to prevent array underflows.
Fixes: afb90dbb5f78 ("dpaa2-eth: Add ethtool support for flow classification")
