ax.25: Update to register_net_sysctl_sz

Browse Source 
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. We hold off the SIZE_MAX to ARRAY_SIZE change until we have
migrated all the relevant net sysctl registering functions to
register_net_sysctl_sz in subsequent commits.
