Liu Shixin 1c5fdf2d46 ubifs: Fix memory leak in ubifs_sysfs_init() 
[ Upstream commit 203a55f04f66eea1a1ca7e5a302a7f5c99c62327 ]

When insmod ubifs.ko, a kmemleak reported as below:

 unreferenced object 0xffff88817fb1a780 (size 8):
   comm "insmod", pid 25265, jiffies 4295239702 (age 100.130s)
   hex dump (first 8 bytes):
     75 62 69 66 73 00 ff ff                          ubifs...

     [<ffffffff88e00087>] entry_SYSCALL_64_after_hwframe+0x63/0xcd

When kset_register() failed, we should call kset_put to cleanup it.
