mtd: core: fix possible resource leak in init_mtd()

I got the error report while inject fault in init_mtd():

Error registering mtd class or bdi: -17

If init_mtdchar() fails in init_mtd(), mtd_bdi will not be unregistered, as a result, we can't load the mtd module again, to fix this by calling bdi_unregister(mtd_bdi) after out_procfs label.
