Subject: [PATCH] HPack: fix a Yoda Condition

Putting the variable on the LHS of a relational operation makes the
expression easier to read. In this case, we find that the whole
expression is nonsensical as an overflow protection, because if
name.size() + value.size() overflows, the result will exactly _not_
be > max() - 32, because UB will have happened.

To be fixed in a follow-up commit.

As a drive-by, add parentheses around the RHS.

Pick-to: 6.7 6.6 6.5 6.2 5.15
