fsnotify: generate pre-content permission event on truncate
Generate FS_PRE_ACCESS event before truncate, without sb_writers held.
Move the security hooks also before sb_start_write() to conform with
other security hooks (e.g. in write, fallocate).
The event will have a range info of the page surrounding the new size
to provide an opportunity to fill the conetnt at the end of file before
truncating to non-page aligned size.
