Variable 'err' is set to -ENOMEM but this value is never read as it is overwritten with a new value later on, hence the 'If statements' and assignments are redundantand and can be removed.
Cleans up the following clang-analyzer warning:
net/ipv6/seg6.c:126:4: warning: Value stored to 'err' is never read [clang-analyzer-deadcode.DeadStores]
