[PATCH 03/10] fsx: use an enum to define the operation commands

["Darrick J. Wong" <darrick.wong@oracle.com>]

From: Darrick J. Wong <darrick.wong@oracle.com>

Use an enum to define operation codes and the boundaries between
operation classes so that we can add new commands without having to
change a bunch of unrelated #defines.
