The panic happens in hfi1ipoibtxreqdeinit() because there is a NULL deref when hfi1ipoibnetdevdtor() is called in this error case.
hfi1ipoibtxreqinit() and hfi1ipoibrxqinit() are self unwinding so fix by adjusting the error paths accordingly.
Other changes: - hfi1ipoibfreerdmanetdev() is deleted including the freenetdev() since the netdev core code deletes calls freenetdev() - The switch to the accelerated entrances is moved to the success path.
