Subject: [PATCH] Revert "ext4: apply umask if ACL support is disabled"

This reverts commit 484fd6c1de13b336806a967908a927cc0356e312.  The
commit caused a regression because now the umask was applied to
symlinks and the fix is unnecessary because the umask/O_TMPFILE bug
has been fixed somewhere else already.
