ARM: kprobes: address gcc -Wempty-body warning

From: Arnd Bergmann <[email protected]>

Building with 'make W=1' shows a warning in some configurations when 'verbose()' is defined to be empty.

arch/arm/probes/kprobes/test-core.c: In function 'kprobes_test_case_start':
arch/arm/probes/kprobes/test-core.c:1367:26: error: suggest braces around empty body in an 'else' statement [-Werror=empty-body]
1367 | current_instruction);
| ^

Change the definition of verbose() to use no_printk(), allowing format string checking and avoiding the warning.
