xtensa: fix build with gcc 13.1.1

New gcc does not understand that the variable 'restore_ms' is set
to 'true' only when the variable 'ms' is assigned in
	static int xtensa_write_dirty_registers(...)
	{
		xtensa_reg_val_t ms;
		bool restore_ms = false;
		...
		if (...) {
			ms = regval;
			restore_ms = true;
			...
		}
		...
		if (restore_ms) {
			USE(ms);
		}
		...
	}
and complains about possible use of uninitialized variable 'ms'.

Sadly initialize 'ms' to zero to hide this false positive.
