ext4: apply umask if ACL support is disabled
commit 484fd6c1de13b336806a967908a927cc0356e312 upstream.
The function ext4_init_acl() calls posix_acl_create() which is
responsible for applying the umask. But without
CONFIG_EXT4_FS_POSIX_ACL, ext4_init_acl() is an empty inline function,
and nobody applies the umask.
This fixes a bug which causes the umask to be ignored with O_TMPFILE
on ext4:
