octeontx2-pf: Fix PFC TX scheduler free

Browse source 
[ Upstream commit a9ac2e18779597f280d68a5b5f5bdd51a34080fa ]

During PFC TX schedulers free, flag TXSCHQ_FREE_ALL was being set
which caused free up all schedulers other than the PFC schedulers.
This patch fixes that to free only the PFC Tx schedulers.
