coccinelle: misc: struct_size: drop unneeded parentheses

Browse Source 
The outer parentheses and the single-branch disjunction don't matter when
just matching and reporting a line. Eliminating them reduces the
complexity of the pattern to match and gives a performance improvement in
the non-patch cases, like the previous minmax change.
