ext4: fix missing iput of root inode for some mount error paths

This assures that the root inode is not leaked, and that sb->s_root is
NULL, which will prevent generic_shutdown_super() from doing extra
work, including call sync_filesystem, which ultimately results in
ext4_sync_fs() getting called with an uninitialized struct super,
which is the cause of the crash noted in Kernel Bugzilla #26752.
