Subject: [TEST]  net/bind_wildcard flakiness

Hi!

The bind_wildcard used to be rock solid, no flakes in last 1000 runs,
but then around the time Eric posted his Rx optimizations we hit one
flake, and now we hit another:

List:
https://netdev.bots.linux.dev/contest.html?test=bind-wildcard&executor=vmksft-net&pass=0

Outputs:
https://netdev-3.bots.linux.dev/vmksft-net/results/122022/14-bind-wildcard/stdout
https://netdev-3.bots.linux.dev/vmksft-net/results/123463/14-bind-wildcard/stdout

One does:

# 0.21 [+0.00] # bind_wildcard.c:768:reuseaddr:Expected ret (-1) == 0 (0)
# 0.21 [+0.00] # reuseaddr: Test terminated by assertion
# 0.21 [+0.00] #          FAIL  bind_wildcard.v6_any_only_v6_v4mapped_any.reuseaddr

The other:

# 0.25 [+0.00] # bind_wildcard.c:775:plain:Expected ret (-1) == 0 (0)
# 0.25 [+0.00] # plain: Test terminated by assertion
# 0.25 [+0.00] #          FAIL  bind_wildcard.v6_local_v6_v4mapped_any.plain


The only change on the infra side is that I increased disk IO cap,
so the builds are now faster.
