fanotify: disable readahead if we have pre-content watches
With page faults we can trigger readahead on the file, and then
subsequent faults can find these pages and insert them into the file
without emitting an fanotify event. To avoid this case, disable
readahead if we have pre-content watches on the file. This way we are
guaranteed to get an event for every range we attempt to access on a
pre-content watched file.
