The radix kremove implementation cleared a kernel PTE without
invalidating its TLB entry. Reusing crashdumpmap could therefore keep
accessing an old physical page, causing minidumps to contain repeated
stale page contents.
Invalidate the removed kernel mapping and synchronize newly installed
kernel PTEs before they are accessed.
