Drivers: hv: util: Fix a bug in the KVP code
commit 9bd2d0dfe4714dd5d7c09a93a5c9ea9e14ceb3fc upstream.
Add code to poll the channel since we process only one message
at a time and the host may not interrupt us. Also increase the
receive buffer size since some KVP messages are close to 8K bytes in size.
