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 initmtdchar() fails in initmtd(), mtdbdi will not be unregistered, as a result, we can't load the mtd module again, to fix this by calling bdiunregister(mtdbdi) after outprocfs label.
