[PATCH] ntfs: avoid incorrectly release for root inode in fill_super

From: Chao Yu
Date: Thu Jul 24 2014 - 22:25:59 EST


In d_make_root, when we fail to allocate dentry for root inode, we will iput
root inode in this function.
So we do not need to release this inode again at d_make_root's caller.
