Drivers: hv: vmbus: Drop error message when 'No request id available'
[ Upstream commit 0c85c54bf7faeb80c6b76901ed77d93acef0207d ]
Running out of request IDs on a channel essentially produces the same
effect as running out of space in the ring buffer, in that -EAGAIN is
returned. The error message in hv_ringbuffer_write() should either be
dropped (since we don't output a message when the ring buffer is full)
or be made conditional/debug-only.
