expr: update EXPR_MAX and add missing comments
WHen flagcmp and catchall expressions got added the EXPR_MAX definition
wasn't changed.
Should have no impact in practice however, this value is only checked to
prevent crash when old nft release is used to list a ruleset generated
by a newer nft release and a unknown 'typeof' expression.
v2: Pablo suggested to add EXPR_MAX into enum so its easier to spot.
Adding __EXPR_MAX + define EXPR_MAX (__EXPR_MAX - 1) causes '__EXPR_MAX
not handled in switch' warnings, hence the 'EXPR_MAX =' solution.
