wifi: rtl8xxxu: Dump the efuse right after reading it
Someone reported a problem with their TP-Link WN722N (RTL8188EUS):
usb 1-1: This Realtek USB WiFi dongle (0x2357:0x010c) is untested!
usb 1-1: Please report results to Jes.Sorensen@gmail.com
usb 1-1: Fatal - failed to parse EFuse
rtl8xxxu: probe of 1-1:1.0 failed with error -22
This error can happen when the first two bytes of the efuse don't have
the expected magic value of 0x8129. In a situation like this it could
be useful to see the contents of the efuse.
Dump the efuse right after reading it, before trying to parse it.
