octeontx2-pf: mcs: Fix mcs resources free on PF shutdown

Browse Source 
On PF shutdown, the current driver free mcs hardware
resources though mcs resources are not allocated to it.
This patch checks the mcs resources status and if resources
are allocated then only sends mailbox message to free them.
