qcacld-3.0: Fix WLAN IPA duplicate deactivation

FW assert is observed when HTT_WDI_IPA_OPCODE_TX_SUSPEND is sent twice
in a row. Issue is that CLIENT_DISCONNECT and AP_DISCONNECT could both
trigger IPA deactivation when CLIENT_DISCONNECT is poped from pending
queue and in another thread AP_DISCONNECT event arrives.

Fix is to add check for resource_unloading flag and if resource_unloading
is set to true, IPA deactivation is ignored since deactivation is already
undergoing.
