Mike Marciniszyn 942a899335 IB/hfi1: Handle port down properly in pio ... The call to sc_buffer_alloc currently returns NULL (no buffer) or a buffer descriptor. There is a third case when the port is down. Currently that returns NULL and this prevents the caller from properly handling the sc_buffer_alloc() failure. A verbs code link test after the call is racy so the indication needs to come from the state check inside the allocation routine to be valid. Fix by encoding the ECOMM failure like SDMA. IS_ERR_OR_NULL() tests are added at all call sites. For verbs send, this needs to treat any error by returning a completion without any MMIO copy.
