psample: Fix user API breakage
Cited commit added a new attribute before the existing group reference
count attribute, thereby changing its value and breaking existing
applications on new kernels.
Before:
# psample -l
libpsample ERROR psample_group_foreach: failed to recv message: Operation not supported
After:
# psample -l
Group Num Refcount Group Seq
1 1 0
Fix by restoring the value of the old attribute and remove the
misleading comments from the enumerator to avoid future bugs.
