net: Namespace-ify sysctl_optmem_max
optmem_max being used in tx zerocopy,
we want to be able to control it on a netns basis.
Following patch changes two tests.
Tested:
oqq130:~# cat /proc/sys/net/core/optmem_max

oqq130:~# echo 1000000 >/proc/sys/net/core/optmem_max
oqq130:~# cat /proc/sys/net/core/optmem_max
1000000
oqq130:~# unshare -n
oqq130:~# cat /proc/sys/net/core/optmem_max
