qcow2: Fix error path for unknown incompatible features
qcow2's report_unsupported_feature() had two bugs: A 32 bit truncation
would prevent feature table entries for bits 32-63 from being used, and
it could assign errp multiple times if there was more than one unknown
feature, resulting in an error_set() assertion failure.
Fix the truncation, make sure to set the error exactly once and add a
qemu-iotests case for it.
This fixes https://bugs.launchpad.net/qemu/+bug/1342704/
