libc: posix_fallocate must return an error number on failure
posix_fallocate implementation in uClibc relies on fallocate system call - it just returns what fallocate returns. However fallocate returns -1 on failure and assigns an error number to errno variable. In the same time posix_fallocate must return an error number but not -1. What does this patch: if fallocate returns -1 then posix_fallocate returns errno. Otherwise posix_fallocate returns 0 on success. However there is a side effect - posix_fallocate sets errno on failure because fallocate does it. But POSIX does not forbid it thus it's not a problem.
