netfilter: nf_tables: remove unneeded conditional
This helper is inlined, so keep it as small as possible.
If the static key is true, there is only a very small chance
that info->trace is false:
1. tracing was enabled at this very moment, the static key was
updated to active right after nft_do_table was called.
2. tracing was disabled at this very moment.
trace->info is already false, the static key is about to
be patched to false soon.
In both cases, no event will be sent because info->trace
is false (checked in noinline slowpath). info->nf_trace is irrelevant.
The nf_trace update is redunant in this case, but this will only
happen for short duration, when static key flips.
