[PATCH] target/riscv: Fix initialized value for cur_pmmask |

We initialize cur_pmmask as -1(UINT32_MAX/UINT64_MAX) and regard it
as if pointer mask is disabled in current implementation. However,
the addresses for vector load/store will be adjusted to zero in this
case and -1(UINT32_MAX/UINT64_MAX) is valid value for pmmask when
pointer mask is enabled.
