[OFED] More WinOF --> OFED name changes. In CheckDriversOK() remove usage of Wsh.Sleep() as it fails in the installer environment. Wait by invoking 'cmd.exe /C timeout /T 2'. Need to wait in a small # of isolated cases for the IPoIB driver (device IBA\IPOIB) to show up in the Window device database. Waiting ensures NetworkDirect/IBAL & Winsock Direct providers install correctly. Wait 30 seconds max, output timed nastyGram about possible IPoIB driver initialization failure (no errors returned).
