Fix cleanup around socketpair() failure to copy out FDs.
- Use the fs.File, rather than the vfs.FileDescription, in the VFS1 version.
- Check for a nil fs.File/vfs.FileDescription before calling DecRef, which is
possible if a racing dup2() or dup3() replaces the file descriptor between
when it is installed and when it is returned. (This is not possible in Linux
because Linux separates allocation of a file descriptor from binding an
allocated file descriptor to a struct file, and dup2/dup3 return EBUSY if
asked to replace an allocated but unbound file descriptor.)
