powerpc64/bpf: fix the address returned by bpf_get_func_ip
commit 157820264ac3dadfafffad63184b883eb28f9ae0 upstream.
bpf_get_func_ip() helper function returns the address of the traced
function. It relies on the IP address stored at ctx - 16 by the bpf
trampoline. On 64-bit powerpc, this address is recovered from LR
accounting for OOL trampoline. But the address stored here was off
by 4-bytes. Ensure the address is the actual start of the traced
function.
