misc: mic: SCIF Fix scif_get_new_port() error handling

There are only 2 callers of scif_get_new_port() and both appear to get
the error handling wrong.  Both treat zero returns as error, but it
actually returns negative error codes and >= 0 on success.

Fixes: e9089f43 ("misc: mic: SCIF open close bind and listen APIs")
