mm/vmalloc: separate put pages and flush VM flags
When VM_MAP_PUT_PAGES was added, it was defined with the same value as VM_FLUSH_RESET_PERMS. This doesn't seem like it will cause any big functional problems other than some excess flushing for VM_MAP_PUT_PAGES allocations. Redefine VM_MAP_PUT_PAGES to have its own value. Also, rearrange things so flags are less likely to be missed in the future.
