Pull vfs fallocate updates from Christian Brauner:
 "This contains work to try and cleanup some the fallocate mode
  handling. Currently, it confusingly mixes operation modes and an
  optional flag.

  The work here tries to better define operation modes and optional
  flags allowing the core and filesystem code to use switch statements
  to switch on the operation mode"
