net: qede: use return from qede_parse_actions()

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

qede_parse_actions() can currently fail with:
* -EINVAL
* -EOPNOTSUPP

This patch changes the code to use the actual
return code, not just return -EINVAL.

The blaimed commit broke the implicit assumption
that only -EINVAL would ever be returned.

Only compile tested.
