Menglong Dong 492e797fda bpf, x86: initialize the variable "first_off" in save_args() 
As Dan Carpenter reported, the variable "first_off" which is passed to
clean_stack_garbage() in save_args() can be uninitialized, which can
cause runtime warnings with KMEMsan. Therefore, init it with 0.

Fixes: 473e3150e3 ("bpf, x86: allow function arguments up to 12 for TRACING")
