Eric Dumazet 677c9ad983 bpf: Fixes possible race in update_prog_stats() for 32bit arches 
[ Upstream commit d979617aa8 ]

It seems update_prog_stats() suffers from same issue fixed
in the prior patch:

As it can run while interrupts are enabled, it could
be re-entered and the u64_stats syncp could be mangled.

Fixes: fec56f5890 ("bpf: Introduce BPF trampoline")
