Fix build errors with gcc 7.2.0 on Gentoo with kernel 4.14
built with CONFIG_GCC_PLUGIN_RANDSTRUCT=y such as:

module/nvpair/nvpair.c:2810:2:error:
positional initialization of field in ?struct? declared with
'designated_init' attribute [-Werror=designated-init]
nvs_native_nvlist,
^~~~~~~~~~~~~~~~~

Signed-off-by: Mark Wright [email protected]

Description

Specify the struct member that is being initialized.

Motivation and Context

Fixes build errors with gcc 7.2.0 on Gentoo with kernel 4.14.2 built with
CONFIG_GCC_PLUGIN_RANDSTRUCT=y such as:

/var/tmp/portage/sys-fs/zfs-kmod-9999/work/zfs-kmod-9999/module/nvpair/nvpair.c:2810:2:error: positional initialization of field in ‘struct’ declared with ‘designated_init’ attribute [-Werror=designated-init]
  nvs_native_nvlist,
  ^~~~~~~~~~~~~~~~~
/var/tmp/portage/sys-fs/zfs-kmod-9999/work/zfs-kmod-9999/module/nvpair/nvpair.c:2810:2: note: (near initialization for ‘nvs_native_ops’)
/var/tmp/portage/sys-fs/zfs-kmod-9999/work/zfs-kmod-9999/module/nvpair/nvpair.c:2810:2:error: invalid initializer
/var/tmp/portage/sys-fs/zfs-kmod-9999/work/zfs-kmod-9999/module/nvpair/nvpair.c:2810:2: note: (near initialization for ‘nvs_native_ops.<anonymous>’)
/var/tmp/portage/sys-fs/zfs-kmod-9999/work/zfs-kmod-9999/module/nvpair/nvpair.c:2811:2:error: positional initialization of field in ‘struct’ declared with ‘designated_init’ attribute [-Werror=designated-init]
  nvs_native_nvpair,
  ^~~~~~~~~~~~~~~~~

How Has This Been Tested?

I built sys-fs/zfs-kmod-9999 patched with these changes, then booted
my Gentoo machine running on zfs with the changes using
sys-kernel/gentoo-sources-4.14.2 built with
CONFIG_GCC_PLUGIN_RANDSTRUCT=y

argus ~ # uname -a
Linux argus 4.14.2-gentoo #1 SMP Mon Nov 27 10:17:35 AEDT 2017 x86_64 Intel(R) Core(TM) i7 CPU X 940 @ 2.13GHz GenuineIntel GNU/Linux
argus ~ # grep CONFIG_GCC_PLUGIN_RANDSTRUCT /usr/src/linux-4.14.2-gentoo/.config
CONFIG_GCC_PLUGIN_RANDSTRUCT=y
CONFIG_GCC_PLUGIN_RANDSTRUCT_PERFORMANCE=y
