Currently, 'pcc_chan_count' is remains set to a non-zero value if PCC subspaces are parsed successfully but something else fail later during the initial PCC probing phase. This will result in pcc_mbox_request_channel trying to access the resources that are not initialised or allocated and may end up in a system crash. Reset pcc_chan_count to 0 when the PCC probe fails in order to prevent the possible issue as described above.
