cnss2: Do not force collect dump during driver loading/unloading

Do not force collect dump during driver loading/unloading as this
will result a deadlock. During driver loading/unloading, if WLAN
host driver detects a hang in FW side, it will try to trigger a
RDDM in FW side by calling platform force collect rddm API. In this
API, it will queue a work in the workqueue to trigger RDDM and wait
until RDDM collection is completed. In this case, driver loading/unloading
can't complete as it blocked by RDDM and RDDM can't be completed
as its work can't be execute until driver loading/unloading is finished.
