qcacmn: Set up TX bank profile for IPA

bank id is newly added in TX descriptor for BE chipsets. As such,
with IPA Offload enabled, IPA needs the bank id information to do
offload WLAN TX.

From WLAN perspective, bank id is designed to be used on a per-vdev
role basis. E.g. STA vdev and SAP vdev have separate and different
bank profiles.

However from IPA perspective, bank id needs to be on a per TX ring
basis, because IPA GSI FW is not able to identify STA or SAP vdev
role on a per-packet basis.

Hence initialize last HOST owned bank id profile for IPA usage.
