Subject: [net PATCH] octeontx2-af: Skip TM tree print for disabled SQs

Currently, the TM tree is printing all SQ topology including those
which are not enabled, this results in redundant output for SQs
which are not active. This patch adds a check in print_tm_tree()
to skip printing the TM tree hierarchy if the SQ is not enabled.

Fixes: b907194a5d5b ("octeontx2-af: Add debugfs support to dump NIX TM topology")
