after 250df6ed274d767da844a5d9f05720b804240197
(fs: protect inode->i_state with inode->i_lock), insert_inode_locked()
no longer returns the inode with I_NEW set on failure.  However,
the error handler still calls unlock_new_inode() on failure,
which does a WARN_ON if I_NEW is not set, so any failure spews
a lot of warnings.

(We also were doing dquot_drop, etc before we had initialized
the quota, that gets skipped as well)

V2: don't rearrange clear_nlink, and edit commit message.
