bpf: Remove obsolete WARN_ON call

Browse source

The WARN_ON call in bpf_trampoline_update could never hit, because we
direct the code path with (total == 0) to out label, which effectively
skips the WARN_ON call.

The WARN_ON made sense back then when it checked tr->selector, but now
with total being set just inside the function it's useless.
