Consider the following sequence of events:

1. A page in a PROT_READ|PROT_WRITE VMA is faulted.
2. Page migration allocates a page with the KASAN allocator, causing it to receive a non-match-all tag, and uses it to replace the page faulted in 1.
3. The program uses mprotect() to enable PROT_MTE on the page faulted in 1.

Applied to arm64 (for-next/fixes), thanks!
