Revert "qdev: Add help for property value"

Browse Source 
This reverts commit 922910ce42d15bdb7c2347436b1b5798b5401de4.

The commit has four issues:

* When it runs from the monitor, e.g. "device_add e1000,mac=?", it
  prints to stderr instead of the monitor.

* Help looks to callers just like failed device creation.  This makes
  main() exit unsuccessfully on "-device e1000,mac=?".

* It has an undocumented side effect on -global: "-global e1000.mac=?"
  prints help, but only when we actually add an e1000 device.

* It does not work for properties that accept the value "?".

We need to do this differently.
