drivers: lkdtm: fix clang -Wformat warning
When building with Clang we encounter the following warning (ARCH=hexagon + CONFIG_FRAME_WARN=0): | ../drivers/misc/lkdtm/bugs.c:107:3: error: format specifies type | 'unsigned long' but the argument has type 'int' [-Werror,-Wformat] | REC_STACK_SIZE, recur_count); | ^~~~~~~~~~~~~~ Cast REC_STACK_SIZE to `unsigned long` to match format specifier `%lu` as well as maintain symmetry with `#define REC_STACK_SIZE (_AC(CONFIG_FRAME_WARN, UL) / 2)`.
