Hangyu Hua 9b90aca97f net: ethernet: bcmasp: fix possible OOB write in bcmasp_netfilt_get_all_active() ...

rule_locs is allocated in ethtool_get_rxnfc and the size is determined by
rule_cnt from user space. So rule_cnt needs to be check before using
rule_locs to avoid OOB writing or NULL pointer dereference.
