Anton Vorontsov 37c4fd8c75 USB: fsl_udc_core: Fix kernel oops on module removal 
fsl_udc_release() calls dma_free_coherent() with an inappropriate
device passed to it, and since the device has no dma_ops, the following
oops pops up:

  Kernel BUG at d103ce9c [verbose debug info unavailable]
  Oops: Exception in kernel mode, sig: 5 [#1]
  ...
  NIP [d103ce9c] fsl_udc_release+0x50/0x80 [fsl_usb2_udc]

  ...

This patch fixes the issue by passing dev->parent, which points to
a correct device.
