usb: dwc3: host: remove dead code in dwc3_host_get_irq()
According to the description of platform_get_irq()
* Return: non-zero IRQ number on success,
negative error number on failure.
and the code, platform_get_irq() will return -EINVAL
instead of IRQ0.
So platform_get_irq() no longer returns 0, there is no
need to check whether the return value is 0.
Found by Smatch:
drivers/usb/dwc3/host.c:60 dwc3_host_get_irq()
warn: platform_get_irq() does not return zero
