riscv: mm: Fix incorrect ASID argument when flushing TLB

BugLink: https://bugs.launchpad.net/bugs/2016877
commit 9a801afd3eb95e1a89aba17321062df06fb49d98 upstream.

Currently, we pass the CONTEXTID instead of the ASID to the TLB flush
function. We should only take the ASID field to prevent from touching
the reserved bit field.
