Subject: mlxsw: spectrum_span: Rename misnamed variable l3edev
Patch-mainline: v4.18-rc1
Git-commit: fc74ecbc293cba27fd8adee7a18fbda2f8d9e285
References: bsc#1112374

Calling the variable l3edev was relevant when neighbor lookup was the
last stage in the simulated pipeline. Now that mlxsw handles bridges and
vlan devices as well, calling it "L3" is a misnomer.

Thus in mlxsw_sp_span_dmac(), rename to "dev", because that function is
just a service routine where the distinction between tunnel and egress
device isn't necessary.

In mlxsw_sp_span_entry_tunnel_parms_common(), rename to "edev" to
emphasize that the routine traces packet egress.
