    Fix unused variable warning in sfxge's ef10_tx.c
    
    With clang 15, the following -Werror warning is produced:
    
        sys/dev/sfxge/common/ef10_tx.c:345:15: error: variable 'eqp' set but not used [-Werror,-Wunused-but-set-variable]
                efx_qword_t *eqp;
                             ^
    
    The 'eqp' variable is passed as an argument to the EFSYS_BAR_WC_WRITEQ()
    macro, but currently this macro ignores the argument, similar to its
    other _esbp argument. Silence the warning by casting the _eqp argument
    to void in the macro.
    
    MFC after:      3 days
    
    (cherry picked from commit a79731b9453320af6fcf5ec16fa5de900dadbce8)
