[PATCH 1/2] staging/rtl8192u: avoid Wempty-body warning

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

This driver has a few disabled diagnostics, which can probably
just get removed, or might still be helpful:

drivers/staging/rtl8192u/r8192U_core.c: In function 'rtl8192_set_rxconf':
drivers/staging/rtl8192u/r8192U_core.c:767:45: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
  767 |                 DMESG("NIC in promisc mode");
      |                                             ^
drivers/staging/rtl8192u/r8192U_core.c: In function 'rtl819xusb_rx_command_packet':
drivers/staging/rtl8192u/r8192U_core.c:883:80: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
  883 |                 DMESG("rxcommandpackethandle819xusb: It is a command packet\n");
      |                                                                                ^

Changing the empty macro to no_printk() to shut up the compiler warnings
and add format string checking.
