Subject: [PATCH] net/qede: fix device stop to remove primary MAC

[ upstream commit 83ade1ebdbfc8211d3cb5c2bc282c3fa396e4a34 ]

This fix is to remove primary MAC filter during dev stop. Without the
fix device start attempt to add the primary MAC fails. Perform MAC set
remove under IS_PF() check.

Fixes: dd28bc8c6ef4 ("net/qede: fix VF port creation sequence")
