IB/hfi1: IOCTL cleanup and refactoring

Hi Doug,

Here is a set of patches that does some code rework to our IOCTL handling from Mike. I have bundled it as a separate series to make handling review feedback easier.

The HFI1 ioctl() function is long and complex. To reduce that complexity the following patch set refactors each IOCTL into a common pattern, and where necessary calls an associated function to handle the specific IOCTL.

Patches can can also be found in my GitHub repo at:
