Submit #1192: KKASSERTs in sys/kern/uipc_{msg,socket}.c are too strict

* Author: rumcic
* Status: New
* Priority: Normal
* Assignee: 
* Category: Kernel
* Target version: 4.2.x
The code for nfs root mounts does not use kmalloc-ed space for some vars, while
some KKASSERTs in the mentioned files only check for the supplied pointers if
they were kmalloc-ed or not.
The attached patch adds a check if the supplied pointers are not in user stack
(if they are in kernel stack) ... since kmalloc-ed space also resides in the
addresses not in user stack, maybe kva_p should be removed (is it used
anywhere else?)?
