fs/direct-io: remove redundant assignment to variable retval

The variable retval is being assigned a value that is not being read,
it is being re-assigned later on in the function. The assignment
is redundant and can be removed.

Cleans up clang scan build warning:
fs/direct-io.c:1220:2: warning: Value stored to 'retval' is never
read [deadcode.DeadStores]
