qcacmn: Fix regression issue for EAPOL fail

This is regression issue.
regression cause I24cddb9d10e4cb675c8375cbd0f589c7718bd680.

Issue happens in get_htc_send_packets, and it is possible
htc_packet_dequeue but hif_pm_runtime_get failed as suspend
state.

Revise to original logical before regression change.
