[PATCH net-next] hyperv: Increase the buffer length for netvsc_channel_cb()

[Haiyang Zhang <haiyangz@microsoft.com>]

When the buffer is too small for a packet from VMBus, a bigger buffer will be
allocated in netvsc_channel_cb() and retry reading the packet from VMBus.
Increasing this buffer size will reduce the retry overhead.
