Most architectures that implement the old-style mmap() with byte offset use 'unsigned long' as the type for that offset, but microblaze and riscv have the off_t type that is shared with userspace, matching the prototype in include/asm-generic/syscalls.h. Make this consistent by using an unsigned argument everywhere. This changes the behavior slightly, as the argument is shifted to a page number, and an user input with the top bit set would result in a negative page offset rather than a large one as we use elsewhere. For riscv, the 32-bit sys_mmap2() definition actually used a custom type that is different from the global declaration, but this was missed due to an incorrect type check.
