Subject: [PATCH v2 12/14] vrf: Update to register_net_sysctl_sz

Move from register_net_sysctl to register_net_sysctl_sz and pass the
ARRAY_SIZE of the ctl_table array that was used to create the table
variable. We need to move to the new function in preparation for when we
change SIZE_MAX to ARRAY_SIZE() in the register_net_sysctl macro.
Failing to do so would erroneously allow ARRAY_SIZE() to be called on a
pointer. The actual change from SIZE_MAX to ARRAY_SIZE will take place
in subsequent commits.
