Suppress possible unused variable warning for icl_soft.c

Browse Source 
With clang 15, the following -Werror warning is produced on i386:

    sys/dev/iscsi//icl_soft.c:1277:6: error: variable 'i' set but not used [-Werror,-Wunused-but-set-variable]
            int i;
                ^

The 'i' variable is used later in the icl_soft_conn_pdu_get_bio()
function, via the PHYS_TO_DMAP() macro. However, on i386 and some other
architectures, this macro is defined to panic immediately, so in those
cases, 'i' is indeed not used. Suppress the warning by marking 'i' as
unused.
