[dpdk-dev] [PATCH] app/proc-info:fix port mask parse bug

[Li Han <han.li1@zte.com.cn>]

parse_portmask return type is int,but global variable
"enabled_port_mask" type is uint32_t.so in proc_info_parse_args
function,when parse_portmask return -1,"enabled_port_mask" will
get a huge value and "if (enabled_port_mask == 0)" will never happen.
