bpf: Add bpf_patch_call_args prototype to include/linux/bpf.h
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")
