[PATCH 3/4] rsocket: Remove the unused variable 'ret'

[Bart Van Assche <bvanassche-HInyCGIudOg@public.gmane.org>]

The variable 'ret' is assigned a value but that value is never used.
This triggers the following compiler warning:

src/rsocket.c:3720:9: warning: variable 'ret' set but not used [-Wunused-but-set-variable]

Hence remove this variable.
