[Mesa-dev] [PATCH 27/56] anv/device: fail to initialize device if we have queues with unsupported flags

[Jason Ekstrand]

From: Iago Toral Quiroga <itoral at igalia.com>

This is not strictly necessary since users should not be requesting any
flags that are not valid for the list of enabled features requested and
we already fail if they attempt to use an unsupported feature, however
it is an easy to implement sanity check that would help developes realize
that they are doing things wrong, so we might as well do it.
