kernel: split the kernel/user inputs in VfsReq

I think I've done this refactor in the opposite direction a few years ago.

This is mostly meant to prepare me for setxattr, which requires two inputs -
coincidentally, one is already going to be a kernel input, and the other will
be an user input, so it works out.

I also just didn't like the previous way it worked, this feels cleaner.
