There are a couple of warnings in this driver when building with W=1:
drivers/net/wireless/intel/iwlegacy/common.c: In function 'il_power_set_mode':
drivers/net/wireless/intel/iwlegacy/common.c:1195:60: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
1195 | il->chain_noise_data.state);
| ^
drivers/net/wireless/intel/iwlegacy/common.c: In function 'il_do_scan_abort':
drivers/net/wireless/intel/iwlegacy/common.c:1343:57: error: suggest braces around empty body in an 'else' statement [-Werror=empty-body]
Change the empty debug macros to no_printk(), which avoids the
warnings and adds useful format string checks.

Building without mesh supports shows a couple of warnings with
'make W=1':
drivers/net/wireless/marvell/libertas/main.c: In function 'lbs_start_card':
drivers/net/wireless/marvell/libertas/main.c:1068:37: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
1068 | lbs_start_mesh(priv);
Change the macros to use the usual "do { } while (0)" instead to shut up
the warnings and make the code a litte more robust.
