FDWrapper: Do not try to close negative file descriptors

It turns out that some of the BPF helper functions return
a negative `errno` value in case of failure, and since we
wrap the return value into a `FDWrapper` right away this
led to a warning from Valgrind about trying to close an
invalid file descriptor.
