generic: routerbootpart: fix compilation on 64-bit

Trying to compile routerbootpart parsers on 64-bit platforms will fail:
drivers/mtd/parsers/routerbootpart.c: In function 'routerboot_find_dynparts':
./include/linux/kern_levels.h:5:25: error: format '%X' expects argument of type 'unsigned int', but argument 3 has type 'size_t' {aka 'long unsigned int'} [-Werror=format=]

  170 |                         pr_err("%s: mtd_read error while parsing (offset: 0x%X): %d\n",

So, lets simply add the length modifier 'z' to fix compilation.
