From: Haibo Chen <haibo.chen@nxp.com>

commit 4091c8206cfd2e3bb529ef260887296b90d9b6a2 upstream.

i_state_flags used on 32-bit archs, need to clear this flag when
alloc inode.
Find this issue when umount ext4, sometimes track the inode as orphan
accidently, cause ext4 mesg dump.

Fixes: acf943e9768e ("ext4: fix checks for orphan inodes")
