cpu/x86/smm: Fix size_t type mismatch in print statement

The 64-bit compiler x86_64-linux-gnu-gcc-10 aborts the build with the
format warning below:

CC         ramstage/cpu/x86/smm/smm_module_loader.o
    src/cpu/x86/smm/smm_module_loader.c: In function 'smm_module_setup_stub':
    src/cpu/x86/smm/smm_module_loader.c:360:70: error: format '%lx' expects argument of type 'long unsigned int', but argument 5 has type 'unsigned int' [-Werror=format=]

          |                                                                    ~~^
          |                                                                      |
          |                                                                      long unsigned int
          |                                                                    %x

As `size_t` is defined as `long unsigned int` in i386-elf (32-bit), the
length modifier `l` matches there. With x86_64-elf/x86_64-linux-gnu
(64-bit) and `-m32` `size_t` is defined as `unsigned int` resulting in a
type mismatch. So, use the correct length modifier `z` for the type
`size_t`.
