He Fengqing 07058fb18d bpf: Fix possible race in inc_misses_counter
[ Upstream commit 0e3135d3bf ]

It seems inc_misses_counter() suffers from same issue fixed in
the commit d979617aa8 ("bpf: Fixes possible race in update_prog_stats()
for 32bit arches"):
As it can run while interrupts are enabled, it could
be re-entered and the u64_stats syncp could be mangled.

Fixes: 9ed9e9ba23 ("bpf: Count the number of times recursion was prevented")
