grep: prefer UNUSED to MAYBE_UNUSED for pcre allocators
We provide custom malloc/free callbacks for the pcre library to use. Those take an extra "data" parameter, but we don't use it. Back when these were added in 513f2b0bbd (grep: make PCRE2 aware of custom allocator, 2019-10-16), we only had MAYBE_UNUSED. But these days we have UNUSED, which we should prefer, as it will let the compiler inform us if the code changes to actually use the parameters. I also moved the annotations to come after the variable name, which is how we typically spell it. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
