ext4: improve extents status tree trace point
This commit improves the trace point of extents status tree. We rename trace_ext4_es_shrink_enter in ext4_es_count() because it is also used in ext4_es_scan() and we can not identify them from the result. Further this commit fixes a variable name in trace point in order to keep consistency with others.
