[ Upstream commit a643bff752dcf72a07e1b2ab2f8587e4f51118be ]
Add bpf_patch_call_args() prototype. This function is called from BPF verifier
and only if CONFIG_BPF_JIT_ALWAYS_ON is not defined. This fixes compiler
warning about missing prototype in some kernel configurations.
Fixes: 1ea47e01ad6e ("bpf: add support for bpf_call to interpreter")
