memblock: Make memblock_{add|remove|free|reserve}() return int and update prototypes
memblock_{add|remove|free|reserve}() return either 0 or -errno but had long as return type. Chage it to int. Also, drop 'extern' from all prototypes in memblock.h - they are unnecessary and used inconsistently (especially if mm.h is included in the picture).
