Justin C. Miller d11dd0c3f9 [kernel] Fix memory clobbering from endpoint ...

The endpoint receive syscalls can block and then write to userspace
memory. Since the current address space may be different after blocking,
make sure to only actually write to the user memory after returning to
the syscall handler - pass values that are on the syscall handler stack
deeper into the kernel.
