qcacld-3.0: Fix WLAN IPA RM enablement

With IPA WDI unified API, IPA PM is used instad of IPA RM
for power/resource management. When checking if IPA RM is
enabled or not, HDD_IPA_RM_ENABLE_MASK is thus not applicable
for WDI unified API.

Fix is to always return true for IPA WDI unified API for power
efficiency.
