lpfc: Fix memory corruption of the lpfc_ncmd->list pointers
lpfc was changing the private pointer that is set/maintained by the nvme_fc transport. This caused two issues: a) the transport, on teardown may erroneous attempt to free whatever address was set; and b) lfpc uses any value set in lpfc_nvme_fcp_abort() and assumes its a valid io request. Correct issue by properly defining a context structure for lpfc. Lpfc also updated to clear the private context structure on io completion. Since this bug caused scrutiny of the way lpfc moves local request structures between lists, also cleaned up list_del()'s to list_del_inits()'s. This is a nvme-specific bug. The patch was cut against the linux-block tree, for-4.12/block tree. It should be pulled in through that tree.
