+rtlwifi: Eliminate udelay calls with too large values
+
+On ARM, compilation of rtlwifi/efuse.c fails with the message:
+ERROR: "__bad_udelay" [drivers/net/wireless/rtlwifi/rtlwifi.ko] undefined!
+On inspection, the faulty calls are in routine efuse_reset_loader(), a
+routine that is never used, and the faulty routine is deleted.
