hwmon: (smpro-hwmon) Improve switch statments in smpro_is_visible()
Clang warns: drivers/hwmon/smpro-hwmon.c:378:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough] default: ^ drivers/hwmon/smpro-hwmon.c:378:2: note: insert 'break;' to avoid fall-through default: ^ break; 1 error generated. Clang is a little more pedantic than GCC, which does not warn when falling through to a case that is just break or return. Clang's version is more in line with the kernel's own stance in deprecated.rst, which states that all switch/case blocks must end in either break, fallthrough, continue, goto, or return. Add the missing break to silence the warning. Additionally, adjust the indentation of a break and add a default case to the inner switch statement.
