[PATCH] fs/ntfs3: Fix error handling in ntfs_new_inode()

[Shigeru Yoshida]

When memory allocation for mi->mrec fails, ntfs_new_inode() calls
iput().  iput() calls ni_write_inode() indirectly, it references
uninitialized mi->mrec, and this causes the kernel crash.  This patch
fixes the issue by making the inode bad before calling iput().
