    Delete useless checks in confparse.c
    
    config_parse_interval() and config_parse_msec_interval() were checking
    whether the variable "ok" (a pointer to an int) was null, rather than
    derefencing it.  Both functions are static, and all existing callers
    pass a valid pointer to those static functions.  The callers do check
    the variables (also confusingly named "ok") whose addresses they pass
    as the "ok" arguments, so even if the pointer check were corrected to
    be a dereference, it would be redundant.
    
    Fixes #22103.
