Zhang Xiaoxu bf0ad007e6 orangefs: Fix sysfs not cleanup when dev init failed 
[ Upstream commit ea60a4ad0c ]

When the dev init failed, should cleanup the sysfs, otherwise, the
module will never be loaded since can not create duplicate sysfs
directory:

  sysfs: cannot create duplicate filename '/fs/orangefs'

  Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-1.fc33 04/01/2014
