arm64: enable PTE type bit in the mask for pte_modify
Caught during Trinity testing. The pte_modify does not allow modification for PTE type bit. This cause the test to hang the system. It is found that the PTE can't transit from an inaccessible page (b00) to a valid page (b11) because the mask does not allow it. This happens when a big block of mmaped memory is set the PROT_NONE, then the a small piece is broken off and set to PROT_WRITE | PROT_READ cause a huge page split.
