[PATCH] transport-helper.c: fix check for size_t < 0 v2

[Nicolas Kaiser <nikai@nikai.net>]

'bytes' is unsigned of type size_t, and can't be negative.
But the assigned write() returns ssize_t, and -1 on error.
For testing < 0, 'bytes' needs to be of a signed type.

Indeed, thanks. Here's a version with ssize_t.
Testsuite did not regress at my place.
