net: mvpp2: cls: Prevent buffer overflow in mvpp2_ethtool_cls_rule_del()
 
The "info->fs.location" is a u32 that comes from the user via the
ethtool_set_rxnfc() function.  We need to check for invalid values to
prevent a buffer overflow.

I copy and pasted this check from the mvpp2_ethtool_cls_rule_ins()
function.
