musb_core: don't call musb_platform_exit() twice

Browse Source 
musb_platform_exit() is called twice from musb_init_controller() iff controller
initialization fails. Move the call (and the DevCtl register writes surrounding
it) from musb_free() to musb_remove().

Fix mispalced and now incorrect 'goto's in musb_init_controller().
