staging: wilc1000: fix return type of wilc_setup_multicast_filter

This patch changes return type of wilc_setup_multicast_filter from s32
to int. The result variable gets return value from wilc_mq_send that has
return type of int. It should be changed return type of this function as
well as data type of result variable.
