Octeontx2-pf: Free send queue buffers incase of leaf to inner
There are two type of classes. "Leaf classes" that are the
bottom of the class hierarchy. "Inner classes" that are neither
the root class nor leaf classes. QoS rules can only specify leaf
classes as targets for traffic.
Root
/ \
/ \
1 2
/\
/ \
4 5
classes 1,4 and 5 are leaf classes.
class 2 is a inner class.
When a leaf class made as inner, or vice versa, resources associated
with send queue (send queue buffers and transmit schedulers) are not
getting freed.
