inotify: inotify.server.walk*() remove unnecessary var

Remove hginside var and the test it relates to:

not( top or not hginside ) == (not top) and hginside, so the only case
when nothing will be yielded is when hginside is True and top is False.

Because of the returns placed upstream, this case will not happen anymore.
We can then safely remove hginside and the (if)s
