Now that we take care not manipulate the live kernel page tables in a way that may lead to TLB conflicts, the case where a table mapping is replaced by a block mapping can no longer occur. So remove the handling of this at the PUD and PMD levels, and instead, BUG() on any occurrence of live kernel page table manipulations that modify anything other than the permission bits. Since mark_rodata_ro() is the only caller where the kernel mappings that are being manipulated are actually live, drop the various conditional flush_tlb_all() invocations, and add a single call to mark_rodata_ro() instead.
