Subject: [PATCH] Drivers: hv: vmbus: Cleanup vmbus_post_msg()

Posting messages to the host can fail because of transient resource
related failures. Correctly deal with these failures and increase the
number of attempts to post the message before giving up.

In this version of the patch, I have normalized the error code to
Linux error code.
