usb: musb: Fix deferred probing

Browse Source 
When platform_get_irq_byname() fails, it may return -EPROBE_DEFER,
which suggested deferred probing, it is very important to propagate it
upstream. We cannot override it with other error code.

Commit ce753ad154 ("platform: finally disallow IRQ0 in
platform_get_irq() and its ilk") makes sure IRQ0 is not returned.
