Josh Boyer reported that my recent change to uapi/linux/swab.h broke the Qemu build:

  bc27fb68aaad ("include/uapi/linux/byteorder, swab: force inlining of some byteswap operations")

Unfortunately, UAPI headers don't include compiler.h so fixing it there is not enough,
add an __always_inline definition to uapi/linux/stddef.h instead.

Testcase: "make headers_install" and try to compile this:

#include <linux/swab.h>
void main() {}
