Suppress unused variable warning in mfi.c

Browse Source 
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.
