wifi: ath12k: refactor DP Rxdma ring structure

Currently data path Rxdma ring structure store the IDR buffer and lock.
These IDR handling is needed only for SW cookie conversion and not
needed for HW cookie conversion. REO Rxdma ring use the HW cookie
conversion and monitor Rxdma ring use the SW cookie conversion.
Since idr not needed for REO Rxdma ring, remove the IDR data entity
from the data path Rxdma ring structure. Introduce the new data path ring
structure for monitor rxmda rings since it need IDR data entity.
