[PATCH -next -v2] ext4: Fix jbd2_journal_shrink_scan() and jbd2_journal_shrink_count() kernel-doc comment

[Yang Li]

Add the description of @shrink and @sc in jbd2_journal_shrink_scan() and
jbd2_journal_shrink_count() kernel-doc comment to remove warnings found
by running scripts/kernel-doc, which is caused by using 'make W=1'.
