[PATCH net-next 3/3] net: qede: use return from qede_flow_parse_ports()

["Asbjørn Sloth Tønnesen" <ast@fiberby.net>]

When calling qede_flow_parse_ports(), then the
return code was only used for a non-zero check,
and then -EINVAL was returned.

qede_flow_parse_ports() can currently fail with:
* -EINVAL

This patch changes qede_flow_parse_v{4,6}_common() to
use the actual return code from qede_flow_parse_ports(),
so it's no longer assumed that all errors are -EINVAL.

Only compile tested.
