2aa0102c6688 ("scsi: ibmvfc: Use correlation token to tag commands")
sets the vfcFrame correlation token to the pointer handle of the associated
ibmvfc_event. However, that commit failed to cast the pointer to an
appropriate type which in this case is a u64. As such sparse warnings are
generated for both correlation token assignments.
ibmvfc.c:2375:36: sparse: incorrect type in argument 1 (different base types)
ibmvfc.c:2375:36: sparse: expected unsigned long long [usertype] val
ibmvfc.c:2375:36: sparse: got struct ibmvfc_event *[assigned] evt
Add the appropriate u64 casts when assigning an ibmvfc_event as a
correlation token.
