driver core: Set default deferred_probe_timeout back to 0.

driver core: Set default deferred_probe_timeout back to 0.

Since we had to effectively reverted
commit 5ffda8808c31 ("driver core: Ensure wait_for_device_probe() waits
until the deferred_probe_timeout fires") in an earlier patch, a non-zero
deferred_probe_timeout will break NFS rootfs mounting [1] again. So, set
the default back to zero until we can fix that.
