## Description

In the Linux kernel, the following vulnerability has been resolved:
IB/hfi1: Fix AIP early init panic

The panic happens in hfi1\_ipoib\_txreq\_deinit() because there is a NULL
deref when hfi1\_ipoib\_netdev\_dtor() is called in this error case.
hfi1\_ipoib\_txreq\_init() and hfi1\_ipoib\_rxq\_init() are self unwinding so
fix by adjusting the error paths accordingly.
Other changes:
- hfi1\_ipoib\_free\_rdma\_netdev() is deleted including the free\_netdev()
since the netdev core code deletes calls free\_netdev()
- The switch to the accelerated entrances is moved to the success path.
