Russell King dd55bfca56 ARM: net: bpf: clarify tail_call index
commit 091f02483df7b56615b524491f404e574c5e0668 upstream.

As per 90caccdd8cc0 ("bpf: fix bpf_tail_call() x64 JIT"), the index used
for array lookup is defined to be 32-bit wide. Update a misleading
comment that suggests it is 64-bit wide.

Fixes: 39c13c204bb1 ("arm: eBPF JIT compiler")
