* win32/win32.c (fileattr_to_unixmode, rb_w32_reparse_symlink_p): volume

mount point should be treated as directory, not symlink.
  [ruby-core:72483] [Bug #11874]

* win32/win32.c (rb_w32_read_reparse_point): check the reparse point is
  a volume mount point or not.

* win32/file.c (rb_readlink): follow above change (but this pass won't
  be used).
