net: Remove the now superfluous sentinel elements from ctl_table array
This commit comes at the tail end of a greater effort to remove the
empty elements at the end of the ctl_table arrays (sentinels) which
will reduce the overall build time size of the kernel and run time
memory bloat by ~64 bytes per sentinel (further information Link :
https://lore.kernel.org/all/ZO5Yx5JFogGi%2FcBo@bombadil.infradead.org/)
* Remove sentinel element from ctl_table structs.
* Remove the zeroing out of an array element (to make it look like a
sentinel) in neigh_sysctl_register and lowpan_frags_ns_sysctl_register
This is not longer needed and is safe after commit c899710fe7f9
("networking: Update to register_net_sysctl_sz") added the array size
to the ctl_table registration.
* Replace the for loop stop condition in sysctl_core_net_init that tests
for procname == NULL with one that depends on array size
* Removed the "-1" in mpls_net_init that adjusted for having an extra
empty element when looping over ctl_table arrays
* Use a table_size variable to keep the value of ARRAY_SIZE
