objtool: Fix STACK_FRAME_NON_STANDARD reloc type
STACK_FRAME_NON_STANDARD results in inconsistent relocation types
depending on .c or .S usage:
Relocation section '.rela.discard.func_stack_frame_non_standard' at offset 0x3c01090 contains 5 entries:
Offset Info Type Symbol's Value Symbol's Name + Addend
0000000000000000 00020c2200000002 R_X86_64_PC32 0000000000047b40 do_suspend_lowlevel + 0
