* Fix FSID of rootfs being 0

For st_dev in struct stat, the value 0 is
  an error. Make sure rootfs has value 1.

  This fixes the coreutils cp -ax issue (although that
  code has already been improved in coreutils, too) and
  somewhat fixes the switch_root problem in util-linux.
  It is still possible that rootfs gets an FSID >1 in
  future versions, so util-linux still needs to be fixed.

  This is unrelated to the mount id issue in
  /proc/*/mountinfo - the mount id may still be
  zero.

* Revert a patch that always enables autosuspend on intel bluetoothh

  xhci still sucks and breaks this. I am reverting this
  commit for reasons that are in no way selfish.

+
+Commit 9e30cc9595303b27b48 removed an internal mount. This
+has the side-effect that rootfs now has FSID 0. Many
+userspace utilities assume that st_dev in struct stat
+is never 0, so this change breaks a number of tools in
+early userspace.
+
+Since we don't know how many userspace programs are affected,
+make sure that FSID is at least 1.
