x86/traps: Print unhashed pointers on stack overflow

When a stack overflow occurs, the kernel prints hashed fault address and the
stack range using %p. The actual addresses are required for debugging and
hashed pointers provide no useful information in this context.

Use %px to print the unhashed, raw addresses.
