etnaviv: always try to create KMS side handles for imported resources

Browse source 
By creating the KMS side handles we allow GBM to return the proper KMS
side GEM handles for imported buffers. Always creating the KMS side
handles adds a bit of overhead, as we don't need them on all imported
resources, but seems like the most robust solution for now.
