bcachefs: Fallocate fixes

Browse source

- fpunch wasn't always correctly updating i_size - when we drop buffered
  writes that were extending a file, we become responsible for writing
  i_size.

- fzero was sometimes zeroing out more data that it should have -
  block_start and block_end were being rounded in the wrong directions
