qcacmn: Skip sanity of sw_cookie in RX error for KIWI

Currently the sw_cookie is validated in RX error path
using the pool_id logic, which is not valid for KIWI target.
Kiwi target has a different logic to assign rx sw_cookie, as
compared to other legacy chipsets.

Hence this sanity of sw_cookie fails always for RX error
packets on KIWI target, and these corresponding buffers are
never released/replenished back. Eventually as more RX error
packets are received, the device runs out of buffers in the
refill ring and induces a backpressure.

Hence disable this sanity check for sw_cookie in rx error
path for KIWI target.
