Huacai Chen 4574815abf LoongArch: Use accessors to page table entries instead of direct dereference

As very well explained in commit 20a004e7b0 ("arm64: mm: Use
READ_ONCE/WRITE_ONCE when accessing page tables"), an architecture whose
page table walker can modify the PTE in parallel must use READ_ONCE()/
WRITE_ONCE() macro to avoid any compiler transformation.

So apply that to LoongArch which is such an architecture, in order to
avoid potential problems.

Similar to commit edf9556472 ("riscv: Use accessors to page table
entries instead of direct dereference").
