jbd2: fix kernel-doc markups

Browse Source 
[ Upstream commit 2bf31d94423c8ae3ff58e38a115b177df6940399 ]

Kernel-doc markup should use this format:
        identifier - description

They should not have any type before that, as otherwise
the parser won't do the right thing.

Also, some identifiers have different names between their
prototypes and the kernel-doc markup.
