Will Deacon 24fe1b0efa arm64: Remove unnecessary ISBs from set_{pte,pmd,pud}
Commit 7f0b1bf045 ("arm64: Fix barriers used for page table modifications")
fixed a reported issue with fixmap page-table entries not being visible
to the walker due to a missing DSB instruction. At the same time, it added
ISB instructions to the arm64 set_{pte,pmd,pud} functions, which are not
required by the architecture and make little sense in isolation.

Remove the redundant ISBs.
