fix: eliminate variadic macro warnings in REQUIRES_OK

Two related warnings were triggered:
- -Wvariadic-macro-arguments-omitted: memory.h called REQUIRES_OK
  with only one argument (no variadic arg)
- -Wgnu-zero-variadic-macro-arguments: macros.h used GNU extension
  '##__VA_ARGS__' to swallow the comma when __VA_ARGS__ was empty

Fix:
1. Add a message argument to the single-arg REQUIRES_OK call site
2. Drop the '##' GNU extension since all call sites now pass at
   least one variadic argument
