nilfs2: Fix some kernel-doc comments

The description of @flags in nilfs_dirty_inode() kernel-doc comment is
missing, and some functions had kernel-doc that used a hash instead of a
colon to separate the parameter name from the one line description.

Fix them to remove some warnings found by running scripts/kernel-doc,
which is caused by using 'make W=1'.
