hyperv: Fix a kernel warning from netvsc_linkstatus_callback()
The warning about local_bh_enable inside IRQ happens when disconnecting a
virtual NIC.
The reason for the warning is -- netif_tx_disable() is called when the NIC
is disconnected. And it's called within irq context. netif_tx_disable() calls
local_bh_enable() which displays warning if in irq.
The fix is to remove the unnecessary netif_tx_disable & wake_queue() in the
netvsc_linkstatus_callback().
