Xiaxi Shen e7abdad660 ext4: fix uninitialized variable in ext4_inlinedir_to_tree ...

[ Upstream commit 8dc9c3da79 ]

Syzbot has found an uninit-value bug in ext4_inlinedir_to_tree

This error happens because ext4_inlinedir_to_tree does not
handle the case when ext4fs_dirhash returns an error

This can be avoided by checking the return value of ext4fs_dirhash
and propagating the error,
similar to how it's done with ext4_htree_store_dirent
