Saurabh Kumar Bansal 7010349a9a usb_host: Hub driver skips fetching string descriptors if their index is 0
When a USB does not support a particular string dsecriptor (e.g.,
manufacturer, product, and serial number), the string descriptors corresponding
index will be set to 0 in the device descriptor (e.g., iManufacturer, iProduct,
iString).

Previously, the Hub driver would always attempt to fetch the all three string
descriptors, thus leading an error in CHECK_SHORT_SER_STR_DESC if the device
did not support the descriptor.

This commit fixes the Hub drvier by skipping the enumeration stages of a
particular descriptor if its index is 0 (i.e., not supported by the device).
