riscv: Reset pmm when PR_TAGGED_ADDR_ENABLE is not set
In set_tagged_addr_ctrl(), when PR_TAGGED_ADDR_ENABLE is not set, pmlen
is correctly set to 0, but it forgets to reset pmm. This results in the
CPU pmm state not corresponding to the software pmlen state.
Fix this by resetting pmm along with pmlen.
