wifi: ath12k: Decrement TID on RX peer frag setup error handling

[ Upstream commit 7c0884fc ]

Currently, TID is not decremented before peer cleanup, during error
handling path of ath12k_dp_rx_peer_frag_setup(). This could lead to
out-of-bounds access in peer->rx_tid[].

Hence, add a decrement operation for TID, before peer cleanup to
ensures proper cleanup and prevents out-of-bounds access issues when
the RX peer frag setup fails.

Found during code review. Compile tested only.
