Update pointer info to include IPC memory.

IPC memory was previously returned as HSA_POINTER_ALLOCATED and
had garbage in the node_id field.  Due to ROCR_VISIBLE_DEVICES
we need to be able to distinguish between imported memory and
regular memory because imported memory may not be owned by an
agent that is visible in the process.  Differentiating these flags
allows the users to expect null agent for the owning agent.
