usb: musb: core: properly free host / device structs in err path

The patch fixes two issues in the error path cleanup:
- in MUSB_PORT_MODE_DUAL_ROLE mode, if musb_gadget_setup() fails we
  never cleanup the host struct earlier allocated.
- if musb_init_debugfs() or sysfs_create_group() fails, then we never
  free the host part initialization, only device part.
