qcacld-3.0: update changes for fully supporting MULTI_IF_NAME

Currently, driver don't fully support MULTI_IF_NAME when two wlan
cards are supported by using two drivers:
1. if two wlan cards are all PCIe, driver can't distinguish
two PCIe cards firmware path.
2. When create hdd sysfs file upper folder, it will repeatly create the
same folder if not use MULTI_IF_NAME to distinguish them. It's not
necessary to distinguish the sub-folder once upper folder is different.
