[PATCH 14/14] xfs: Change xfs_xattr_class from a TRACE_EVENT() to DECLARE_EVENT_CLASS()

[Steven Rostedt]

From: Steven Rostedt <rost...@goodmis.org>

xfs_xattr_class was accidentally created as a TRACE_EVENT() instead of a
class with DECLARE_EVENT_CLASS().

Note, TRACE_EVENT() is just defined as:

 #define TRACE_EVENT(name, proto, args, tstruct, assign, print) \
        DECLARE_EVENT_CLASS(name,                              \
                             PARAMS(proto),                    \
                             PARAMS(args),                     \
                             PARAMS(tstruct),                  \
                             PARAMS(assign),                   \
                             PARAMS(print));                   \
        DEFINE_EVENT(name, name, PARAMS(proto), PARAMS(args));

The difference between TRACE_EVENT() and DECLARE_EVENT_CLASS() is that
TRACE_EVENT() also creates an event with the class name.

Switch xfs_xattr_class over to being a class and not an event as it is not
called directly, and that event with the class name takes up unnecessary
memory.
