qed: Fix setting of incorrect eswitch mode.
[ Upstream commit 538f8d00ba8bb417c4d9e76c61dee59d812d8287 ]
By default, driver sets the eswitch mode incorrectly as VEB (virtual
Ethernet bridging).
Need to set VEB eswitch mode only when sriov is enabled, and it should be
to set NONE by default. The patch incorporates this change.
Fixes: 0fefbfbaa ("qed*: Management firmware - notifications and defaults")
