usb: dwc3: qcom: simplify error check in dwc3_qcom_find_num_ports()

The platform_get_irq_byname_optional() function returns a non-zero
IRQ number on success and a negative error code on failure. It
never returns zero.

The current implementation in the modern dwc3-qcom driver checks for
a return value less than or equal to zero. Since zero is not a
valid return value, simplify the check to only look for negative
error codes. This aligns the logic with the standard return contract
of the platform IRQ APIs.
