[PATCH net-next v5 6/6] net: dsa: microchip: fix tag_ksz egress mask for KSZ8795 family

[vtpieter@gmail.com]

From: Pieter Van Trappen <pieter.van.trappen@cern.ch>

Fix the tag_ksz egress mask for DSA_TAG_PROTO_KSZ8795, the port is
encoded in the two and not three LSB. This fix is for completeness,
for example the bug doesn't manifest itself on the KSZ8794 because bit
2 seems to be always zero.
