Variable 'ret' is set to zero 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:
drivers/net/tun.c:3008:2: warning: Value stored to 'ret' is never read [clang-analyzer-deadcode.DeadStores]
