If you're trying to do adhoc mode, then you probably don't need hostapd.
The hostap _daemon_ is a software infrastructure (not adhoc!) mode
access point daemon.  It makes your card become an access point, which
isn't adhoc mode.

If you want adhoc mode, just set the card to adhoc mode and do whatever
you want to do, hostapd itself doesn't need to be involved.
