IB/core: Fix false search of the IB_SA_WELL_KNOWN_GUID
When virtualziation is supported, VFs may send SA MADs to a GID formed
by the concatenation of the subnet prefix with the
IB_SA_WELL_KNOWN_GUID. When a response is required, the current code
will search the local HCA's port for the received GID to figure out the
GID index of the entry containing this GID. However, since this is not a
real GID it will not be found and error will be printed.
We change the logic to check if the destination GID is this special GID
and avoid lookup in this case and use GID index 0.
