staging: lustre: lnet: conrpc: Use list_for_each_entry_safe 

Doubly linked lists which are  iterated  using list_empty
and list_entry macros have been replaced with list_for_each_entry_safe
macro.
This makes the iteration simpler and more readable.

This patch replaces the while loop containing list_empty and list_entry
with list_for_each_entry_safe.

This was done with Coccinelle.

{
...when != T *I1;
- I1 = list_entry(E1.next, T, I2);
...
}
