[PATCH net-next] net: dsa: mv88e6xxx: fix shift of FID bits in mv88e6250_g1_vtu_loadpurge()

[Rasmus Villemoes]

The comment is correct, but the code ends up moving the bits four
places too far, into the VTUOp field.

Fixes: bec8e5725281 (net: dsa: mv88e6xxx: implement vtu_getnext and 
vtu_loadpurge for mv88e6250)
