Sponsored by: iXsystems Inc. r335050: While I was investigating CID 1194192 related with a resource leak on mrp memory allocation, I could identify that actually we use this pointer on pci_emul.c as well as on vga.c source file. I have reworked the logic here to make it more readable and also add a warn to explicit show the function where the memory allocation error could happen, also sort headers. Also CID 1194192 was marked as "Intentional". Obtained from: TrueOS Sponsored by: iXsystems Inc.
