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:

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().
