[PATCH net-next] bonding: convert num_grat_arp to the new bonding option API

[Nikolay Aleksandrov <razor@blackwall.org>]

From: Nikolay Aleksandrov <nikolay@cumulusnetworks.com>

num_grat_arp wasn't converted to the new bonding option API, so do this
now and remove the specific sysfs store option in order to use the
standard one. num_grat_arp is the same as num_unsol_na so add it as an
alias with the same option settings. An important difference is the option
name which is matched in bond_sysfs_store_option().
