Azure: Deprecate Netvsc and implement MANA direct

[Tim Gardner]

SRU Justification

[Impact]

Microsoft has asked for the inclusion of 3 patches that deprecate the use of netvsc in favor of MANA direct.

hv_netvsc: Mark VF as slave before exposing it to user-mode: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/drivers/net/hyperv?id=c807d6cd089d2f4951baa838081ec5ae3e2360f8

hv_netvsc: Fix race of register_netdevice_notifier and VF register: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/drivers/net/hyperv?id=85520856466ed6bc3b1ccb013cddac70ceb437db

hv_netvsc: fix race of netvsc and VF register_netdevice: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/drivers/net/hyperv?id=d30fb712e52964f2cf9a9c14cf67078394044837

[Test Plan]

Microsoft tested

[Regression potential]

User space that relies on netvsc will likely fail
