kdb: address -Wformat-security warnings
[ Upstream commit 70867efacf4370b6c7cdfc7a5b11300e9ef7de64 ]
When -Wformat-security is not disabled, using a string pointer
as a format causes a warning:
kernel/debug/kdb/kdb_io.c: In function 'kdb_read':
kernel/debug/kdb/kdb_io.c:365:36: error: format not a string literal and no format arguments [-Werror=format-security]
365 | kdb_printf(kdb_prompt_str);
| ^~~~~~~~~~~~~~
kernel/debug/kdb/kdb_io.c: In function 'kdb_getstr':
kernel/debug/kdb/kdb_io.c:456:20: error: format not a string literal and no format arguments [-Werror=format-security]
456 | kdb_printf(kdb_prompt_str);
| ^~~~~~~~~~~~~~
Use an explcit "%s" format instead.
