Andreas Kling 094b88e6a5 Kernel: Don't remap already non-writable regions when they become CoW 
The only purpose of the remap() in Region::try_clone() is to ensure
non-writable page table entries for CoW regions. If a region is already
non-writable, there's no need to waste time updating the page tables.
