Dan Carpenter d5c7b42c9f Drivers: hv: vmbus: Use after free in __vmbus_open() ...

[ Upstream commit 3e9bf43f7f7a46f21ec071cb47be92d0874c48da ]

The "open_info" variable is added to the &vmbus_connection.chn_msg_list,
but the error handling frees "open_info" without removing it from the
list.  This will result in a use after free.  First remove it from the
list, and then free it.
