[PATCH] riscv: mm: refactor by introducing trace_page_fault_entries()

[Austin Kim]

From: Austin Kim <austin.kim at lge.com>

Introduce trace_page_fault_entries() as an inline helper to wrap page 
faults tracepoints. This simplifies handle_page_fault() and makes the code 
cleaner and more readable. No functional change is made.
