[PATCH net-next 7/7] ipvs: use type-safe allocation helpers in ip_vs_rht_alloc

[Pablo Neira Ayuso <pablo@netfilter.org>]

From: Subasri S <subasris1210@gmail.com>

As per Documentation/process/deprecated.rst, open-coded kmalloc
assignments for struct objects are deprecated. Replace
kzalloc(sizeof(*ptr), GFP_KERNEL) with kzalloc_obj() and
kvmalloc_array(n, sizeof(*ptr), GFP_KERNEL) with kvmalloc_objs()
in ip_vs_rht_alloc().

Compile tested with CONFIG_IP_VS=y and runtime tested using
tools/testing/selftests/net/netfilter/ipvs.sh on x86_64/QEMU.
