x86: Fix build regression with CONFIG_KEXEC_JUMP enabled
Build 6.13-rc12 for x86_64 with gcc 14.2.1 fails with the error:
ld: vmlinux.o: in function `virtual_mapped':
linux/arch/x86/kernel/relocate_kernel_64.S:249:(.text+0x5915b): undefined reference to `saved_context_gdt_desc'
when CONFIG_KEXEC_JUMP is enabled.
This was introduced by commit 07fa619f2a40 ("x86/kexec: Restore GDT on
return from ::preserve_context kexec") which introduced a use of
saved_context_gdt_desc without a declaration for it.
Fix that by including asm/asm-offsets.h where saved_context_gdt_desc
is defined (indirectly in include/generated/asm-offsets.h which
asm/asm-offsets.h includes).
Fixes: 07fa619f2a40 ("x86/kexec: Restore GDT on return from ::preserve_context kexec")
