core: fix offset calculation in param_mem_to_user_va()

In param_mem_to_user_va() the offset of a memory parameter is used to
check if a particular struct vm_region will cover that parameter.
struct vm_region always uses offsets from the beginning of the first
physical page while a memory parameter contains only the offset from the
beginning of a MOBJ. Consequently the two offset cannot be compared
directly.

Until this patch the two offset where compared directly so fix it by
adding the phys_offs of the MOBJ to the offset of the memory parameter.

Note that this doesn't change the computed virtual address, it only
fails to find a matching struct vm_region under certain circumstances.
