usb: dwc3: core: move dwc3_cache_hwparams before dwc3_alloc_event_buffers
commit 392142 moved event buffer allocation out of dwc3_core_init() but event buffer allocation uses the cached copy of hwparams to determine the number of event buffers and the caching is done in dwc3_core_init. So moved dwc3_cache_hwparams function before dwc3_alloc_event_buffers so that dwc3_alloc_event_buffers sees the correct number of event buffers.
