x86/boot/64: Strip percpu address space when setting up GDT descriptors
init_per_cpu_var() returns a pointer in the percpu address space while
rip_rel_ptr() expects a pointer in the generic address space.
When strict address space checks are enabled, GCC's named address space
checks fail:
asm.h:124:63: error: passing argument 1 of 'rip_rel_ptr' from
pointer to non-enclosed address space
Add a explicit cast to remove address space of the returned pointer.
Fixes: 11e36b0f7c21 ("x86/boot/64: Load the final kernel GDT during early boot directly, remove startup_gdt[]")
