ext4: propagate errors up to ext4_find_entry()'s callers If we run into some kind of error, such as ENOMEM, while calling ext4_getblk() or ext4_dx_find_entry(), we need to make sure this error gets propagated up to ext4_find_entry() and then to its callers. This way, transient errors such as ENOMEM can get propagated to the VFS. This is important so that the system calls return the appropriate error, and also so that in the case of ext4_lookup(), we return an error instead of a NULL inode, since that will result in a negative dentry cache entry that will stick around long past the OOM condition which caused a transient ENOMEM error.
