fs/ntfs3: Fix 'proc_info_root' leak when init ntfs failed

There's a issue as follows:
  proc_dir_entry 'fs/ntfs3' already registered
  WARNING: CPU: 3 PID: 9788 at fs/proc/generic.c:375 proc_register+0x418/0x590
  Modules linked in: ntfs3(E+)
  Call Trace:
   <TASK>
   _proc_mkdir+0x165/0x200
   init_ntfs_fs+0x36/0xf90 [ntfs3]
   do_one_initcall+0x115/0x6c0
   do_init_module+0x253/0x760

   __x64_sys_finit_module+0xbf/0x130
   do_syscall_64+0x72/0x1c0

Above issue happens as missing destroy 'proc_info_root' when error
happens after create 'proc_info_root' in init_ntfs_fs().
So destroy 'proc_info_root' in error path in init_ntfs_fs().
