[libvirt] [PATCH 1/2] syncNicRxFilterMultiMode: Check for helper's retval properly
There are two functions called from syncNicRxFilterMultiMode:
virNetDevSetRcvAllMulti() and virNetDevSetRcvMulti(). Both of
them return 0 on success and -1 on error. However, currently
their return value is checked for != 0 which conflicts with our
assumptions on retvals: a positive value is still considered
success but with current check it would lead to failure.
