riscv: mm: Fix VA base for canonical addresses

RISC-V defines the following virtual address rules:
- For Sv39 (39-bit VA), bits 63–39 all equal to bit 38 of VA
- For Sv48 (48-bit VA), bits 63–48 all equal to bit 47 of VA
- For Sv57 (57-bit VA), bits 63–57 all equal to bit 56 of VA

In other words, the most-significant bits of VA base must be all one if
the highest SvXX address bit of VA is one.
