net: hns3: change GL update rate
The interrupt coalescing self-adaptive function updates the int_gl every
interrupt. The GL update rate is too faster to get a better new GL value.
This patch changes the GL update rate to every one hundred interrupts.
The GL update rate is defined by HNS3_INT_ADAPT_DOWN_START.
