Currently, 'pcc_chan_count' is a non-zero value if PCC subspaces are parsed successfully and subsequent processes is failure during initializing PCC process. This may cause that pcc_mbox_request_channel() can still be executed successfully , which will misleads the caller that this channel is available.
