[PATCH v6 04/19] fsck.c: rename variables in fsck_set_msg_type() for less confusion

[Ævar Arnfjörð Bjarmason <avarab@xxxxxxxxx>]

Rename variables in a function added in 0282f4dced0 (fsck: offer a
function to demote fsck errors to warnings, 2015-06-22).

It was needlessly confusing that it took a "msg_type" argument, but
then later declared another "msg_type" of a different type.

Let's rename that to "severity", and rename "id" to "msg_id" and
"msg_id" to "msg_id_str" etc. This will make a follow-up change
smaller.

While I'm at it properly indent the fsck_set_msg_type() argument list.
