wifi: rtl8xxxu: remove rtl8xxxu_ prefix from filenames
The driver is already in a directory named rtl8xxxu, there's no need to duplicate that in the filename as well. Now file listing looks a lot more reasonable: 8188e.c 8192c.c 8192f.c 8723a.c core.c Makefile rtl8xxxu.h 8188f.c 8192e.c 8710b.c 8723b.c Kconfig regs.h No functional changes, compile tested only.
