bpf, x86: Fix trampoline stack size for 128-bit arguments
In the Linux kernel, the following vulnerability has been resolved: bpf, x86: Fix trampoline stack size for 128-bit arguments btf_distill_func_proto() accepts a function argument up to 16 bytes, so a 128-bit scalar such as __int128 reaches the x86 trampoline with arg_size == 16. But the current implementation assumes an __int128 argument only needs one register, so the register save area is under-allocated and save_args() overwrites adjacent stack slots. Compute the register count from arg_size for all arguments to fix it.
