ext2: Match up ext2_put_page() with ext2_dotdot() and ext2_find_entry()
ext2_dotdot() and ext2_find_entry() both require ext2_put_page() to be
called after successful return. For some of the calls this
corresponding put was hidden in ext2_set_link and ext2_delete_entry().
Match up ext2_put_page() with ext2_dotdot() and ext2_find_entry() in the
functions which call them. This makes the code easier to follow
regarding the get/put of the page.
Clean up comments to match new behavior.
