When CONFIG_PRINTK is not set, the CMPXCHG_BUGCHECK() macro calls
_printk(), but _printk() is a static inline function, not available
as an extern.
Since the purpose of the macro is to print the BUGCHECK info,
make this config option depend on PRINTK.
Fixes multiple occurrences of this build error:
../include/linux/printk.h:208:5: error: static declaration of '_printk' follows non-static declaration
208 | int _printk(const char *s, ...)
| ^~~~~~~

146 | extern int _printk(const char *fmt, ...);
