IB/mad: Fix incorrect access to items on local_list
In cancel_mads(), MADs are moved from the wait_list and local_list to a cancel_list for processing. However, the structures on these two lists are not the same. The wait_list references struct ib_mad_send_wr_private, but local_list references struct ib_mad_local_private. Cancel_mads() treats all items moved to the cancel_list as struct ib_mad_send_wr_private. This leads to a system crash when requests are moved from the local_list to the cancel_list. Fix this by leaving local_list alone. All requests on the local_list have completed are just awaiting processing by a queued worker thread. Bug (crash) reported by Dotan Barak <dotanb@dev.mellanox.co.il>. Problem with local_list access reported by Robert Reynolds <rreynolds@opengridcomputing.com>.
