bpf: Avoid warning when re-casting __bpf_call_base into __bpf_call_base_args
[ Upstream commit 6943c2b05bf09fd5c5729f7d7d803bf3f126cb9a ]
BPF interpreter uses extra input argument, so re-casts __bpf_call_base into
__bpf_call_base_args. Avoid compiler warning about incompatible function
prototypes by casting to void * first.
Fixes: 1ea47e01ad6e ("bpf: add support for bpf_call to interpreter")
