qcacld-3.0: Fix out-of-order completion variable usage

hdd_wlan_get_ibss_peer_info() and hdd_wlan_get_ibss_peer_info_all()
initialize their completion variables after scheduling work, leading to
a race condition that can cause the completion variable to be set before
it is initialized. Reorder the operations so work is scheduled after
initializing the completion variables.
