qcacmn: Fix core_ctl_set_boost not released issue

hdd_napi_serialize(0) will call hif_napi_event() with
NAPI_EVT_USR_NORMAL mode. But in this mode, blacklist_pending
is not set as BLACKLIST_OFF_PENDING, so the function
hif_napi_core_ctl_set_boost(false) is not called.
Then core_ctl can not resume to normal status, which
will result in performance and power issues.
