Introspect, and one Ping. The Introspect gets the correct
error reply, but when dbus-daemon enters
bus_activation_activate_service() for the Ping call, it
sees that there is a pending activation and does an
early-return. The pending activation does not finish

reader_init: Initialize all fields of struct DBusTypeReader (CID 54754, 54772, 54773).

This patch is based on the fix for 'Field reader.array_len_offset is
uninitialized'

Reported by Coverity: CID 54754, 54772, 54773: Uninitialized scalar
variable (UNINIT)

[smcv: also re-order how the class is set when we recurse, so that
the sub-reader's class doesn't end up NULL]

Revert "reader_init: Initialize all fields of struct DBusTypeReader (CID 54754, 54772, 54773)."

This reverts commit 21a7873f20145d561c2de8f084d98200a8de2c83.

This appears to cause a segfault, presumably resulting from something
assuming that reader_init() would not reinitialize all fields:
