Overview:
The LBA Range Type feature is defined as optional in the spec, but the driver currently fails to complete enumeration if the Get Features request for LBA Range Type fails.  Based on the serious nature of the failure, this could be a problem at the upcoming plugfest.  There will likely be devices at plugfest that do not support LBA Range Type, thus causing the OFA driver to not load on these devices.

Files Modified:
In nvmeInit.c, NVMeSetFeaturesCompletion(), the LBA Range Type Get Features request is treated as mandatory and will cause enumeration to fail if the Get Features command is not successful.  This change looks at the status codes and will allow enumeration to continue if the device returns Invalid.
