python/qmp: remove pylint workaround from legacy.py

Pylint upgraded recently (2.13.z) and having a pylint: disable comment
in the middle of an argument field causes it some grief (It appears to
stop parsing when it encounters it, causing some syntax problems). Since
the duplicate line threshold was bumped up in 22305c2, we don't
need this workaround anymore. Drop it.
