net: qede: use return from qede_parse_actions() for flow_spec

In qede_flow_spec_to_rule(), 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

Commit 319a1d19471e ("flow_offload: check for
basic action hw stats type") broke the implicit
assumption that it could only fail with -EINVAL,
by changing it to return -EOPNOTSUPP, when hardware
stats are requested.

However AFAICT it's not possible to trigger
qede_parse_actions() to return -EOPNOTSUPP, when
called from qede_flow_spec_to_rule(), as hardware
stats can't be requested by ethtool_rx_flow_rule_create().

This patch changes qede_flow_spec_to_rule() to use
the actual return code from qede_parse_actions(),
so it's no longer assumed that all errors are -EINVAL.

Only compile tested.
