staging: ks7010: call 'hostif_mib_set_request_int' instead of 'hostif_mib_set_request_bool'

'hostif_mib_set_request_bool' function receives a bool as value and
send the received value with MIB_VALUE_TYPE_BOOL type. There is
one case where the value passed is not a boolean one but
'MCAST_FILTER_PROMISC' which is '2'. Call hostif_mib_set_request_int
instead for related multicast enumeration. This changes original
code behaviour but seems to be the right way to do this.
