[PATCH] Drivers: hv: connection: Remove create_workqueue

[Bhaktipriya Shridhar <bhaktipriya96@gmail.com>]

alloc_workqueue replaces deprecated create_workqueue().
A dedicated workqueue has been used since the workitem (viz &ctx->work,
which maps to vmbus_onmessage_work), is engaged in normal device
operation which involves invoking the handler for channel protocol
messages. WQ_MEM_RECLAIM has been set to guarantee forward progress under
memory pressure, which is a requirement in this case.
Since there are only a fixed number of work items, explicit concurrency
limit is unnecessary here.
