Currently in monitor mode, links are released to WBM through the
SW2WBM_RELEASE ring and WBM will feed the links back to RXDMA
through the WBM2RXDMA_LINK_RING.
WCN6450 uses SOFTUMAC architecture where WBM is not present.
Hence the WBM2RXDMA_LINK_RING is repurposed to SW2RXDMA_LINK_RING
where host will directly release the links to RXDMA using this ring.

Refactor DP rings related code to different files, such that
