[Minios-devel] [UNIKRAFT v2] lib/ukmmap: Fix return type and mark stub parameters as unused for cleaner build

[Felipe Huici <felipe.huici@xxxxxxxxx>]

Fix the return type of mremap and add __unused to its paramters to
prevent unused parameter warnings to appear in the build (mremap is a
stub for now).
