commit 0d2dd7eaed1dac07b266ca2c662ff4a184a3060f upstream.

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.
