mailbox: bcm-pdc: PDC driver leaves debugfs files after removal
Minor fix to ensure that debugfs stats pseudo-files are removed when driver module is unloaded. Previously, the call to debugfs_remove_recursive() was never being called since the directory was not empty, and a seg fault would occur if another process tried to access these leftover files.
