docs: ignore __counted_by attribute in structure definitions

kernel-doc appeared to ignore __counted_by, but appearances can be
deceiving; it caused member names to not be recognized, which manifested as
a number of spurious "Excess struct member" warnings.  Filter that
attribute out and reduce the warning onslaught slightly.
