	The fallthrough comment is not enough to silence the warning with -Wimplicit-fallthrough=5. This commit also fixes submodule handling in github actions.

 | |
|  *
 | |
|  * Compiler specific macro definitions.
 | |
|  *
 | |
|  * WSREP_NOEXCEPT - Specifies that the method/function does not throw. If
 | |
|  *                  and exception is thrown inside, std::terminate is called
 | |
|  *                  without propagating the exception.
 | |
|  *                  Set to "noexcept" if the compiler supports it, otherwise
 | |
|  *                  left empty.
 | |
|  * WSREP_NORETURN - Indicates that the method/function does not return.
 | |
|  *                  Set to attribute "[[noreturn]]" if the compiler supports,
 | |
|  *                  it, otherwise "__attribute__((noreturn))".
 | |
|  * WSREP_OVERRIDE - Set to "override" if the compiler supports it, otherwise
 | |
|  *                  left empty.
 | |
|  * WSREP_UNUSED - Can be used to mark variables which may be present in
 | |
|  *                debug builds but not in release builds.
 | |
|  * WSREP_FALLTHROUGH - Silence implicit fallthrough warning.
