Subject: sfc: remove redundant variable old_vlan
Patch-mainline: v4.19-rc1
Git-commit: 2e6dde5c618f847fdb811373ad520cdb3a4425ab
References: bsc#1105555 FATE#326117

Variable old_vlan is being assigned but is never used hence it is
and can be removed.

Cleans up clang warning:
warning: variable 'old_vlan' set but not used [-Wunused-but-set-variable]
