Description

The issue found by gcc 8 build:

    ../../common/inet/mi.c: In function 'mi_timer':
    ../../common/inet/mi.c:1127:26: error: cast between incompatible function types from 'int (*)(struct mtb_s *)' to 'void (*)()' [-Werror=cast-function-type]
       mtb->mtb_tid = timeout((pfv_t)mi_timer_fire, mtb, tim);
                              ^
    ../../common/inet/mi.c: In function 'mi_timer_move':
    ../../common/inet/mi.c:1256:26: error: cast between incompatible function types from 'int (*)(struct mtb_s *)' to 'void (*)()' [-Werror=cast-function-type]
       mtb->mtb_tid = timeout((pfv_t)mi_timer_fire, mtb, tim);
                              ^
    ../../common/inet/mi.c: In function 'mi_timer_valid':
    ../../common/inet/mi.c:1343:27: error: cast between incompatible function types from 'int (*)(struct mtb_s *)' to 'void (*)()' [-Werror=cast-function-type]
        mtb->mtb_tid = timeout((pfv_t)mi_timer_fire,
                               ^
    cc1: all warnings being treated as errors

The callback for timeout() is not function returning int, but void ()(void), we have no reason to pass something else there.

Tested by checking disassemblies of affected mi_* functions. Only noted differences were in line numbers passed to assfail().
