Variable retval 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:

fs/direct-io.c:1245:2: warning: Value stored to 'retval' is never read
[clang-analyzer-deadcode.DeadStores].
