bpf, x86: Avoid repeated usage of bpf_prog->aux->stack_depth

Browse source

[ Upstream commit f4b21ed0b9 ]

Refactor the code to avoid repeated usage of bpf_prog->aux->stack_depth
in do_jit() func. If the private stack is used, the stack_depth will be
0 for that prog. Refactoring make it easy to adjust stack_depth.
