History
Andrew Turner 01ffedf593 Unwire the kcov buffer when freeing the info struct. 
Without this the physical memory will not be returned to the kernel.

While here call vm_object_reference on the object when mmapping the buffer.
This removed the need for buggy tracking of if it has been mapped or not.

This fixes issues where kcov could use all the system memory.
