ocfs2: free inode when ocfs2_get_init_inode() fails

[ Upstream commit 965b5dd1894f4525f38c1b5f99b0106a07dbb5db ]

syzbot is reporting busy inodes after unmount, for commit 9c89fe0af826
("ocfs2: Handle error from dquot_initialize()") forgot to call iput() when
new_inode() succeeded and dquot_initialize() failed.
