Variable err is set to -ENOMEM but this value is never read as it is overwritten with a new value later on, hence it is a redundant assignment and can be removed.
Cleans up the following clang-analyzer warning:
net/mpls/af_mpls.c:1022:2: warning: Value stored to 'err' is never read [clang-analyzer-deadcode.DeadStores].
