netfs: Update i_blocks when write committed to pagecache

Update i_blocks when i_size is updated when we finish making a write to the
pagecache to reflect the amount of space we think will be consumed.

This maintains cifs commit dbfdff402d89854126658376cbcb08363194d3cd ("smb3:
update allocation size more accurately on write completion") which would
otherwise be removed by the cifs part of the netfs writeback rewrite.
