orangefs: free superblock when mount fails
Otherwise lockdep says: [ 1337.483798] ================================================ [ 1337.483999] [ BUG: lock held when returning to user space! ] [ 1337.484252] 4.11.0-rc6 #19 Not tainted [ 1337.484423] ------------------------------------------------ [ 1337.484626] mount/14766 is leaving the kernel with locks still held! [ 1337.484841] 1 lock held by mount/14766: [ 1337.485017] #0: (&type->s_umount_key#33/1){+.+.+.}, at: [<ffffffff8124171f>] sget_userns+0x2af/0x520 Caught by xfstests generic/413 which tried to mount with the unsupported mount option dax. Then xfstests generic/422 ran sync which deadlocks.
