[PATCH] usb: gadget: udc: bcm63xx: Propagate iudma_init() error code

[Xiangwu Lai]

bcm63xx_init_udc_hw() calls iudma_init() and stores the return code
in rc, but then returns 0 unconditionally.  When iudma_init() fails,
the hardware has already been torn down by bcm63xx_uninit_udc_hw(),
yet the probe believes initialization succeeded and goes on to
register a gadget controller with non-functional IUDMA channels.

Return rc so the probe fails and reports the real error.
