    Suppress unused variable warning in mfi.c
    
    With clang 15, the following -Werror warnings are produced:
    
        sys/dev/mfi/mfi.c:3698:6: error: variable 'timedout' set but not used 
[-Werror,-Wunused-but-set-variable]
                int timedout;
                    ^
        sys/dev/mfi/mfi.c:3742:6: error: variable 'timedout' set but not used 
[-Werror,-Wunused-but-set-variable]
                int timedout = 0;
                    ^
    
    Here, 'timedout' are variables that are only used when debugging,
    requiring #if 0 statements to be modified. Mark the variables as
    potentially unused, to suppress the warnings.
