[PATCH] octeontx2-af: Fix use of uninitialized pointer bmap

If req->ctype does not match any of NIX_AQ_CTYPE_CQ, NIX_AQ_CTYPE_SQ or NIX_AQ_CTYPE_RQ, pointer bmap will remain uninitialized and be accessed in test_bit(), which can lead to kernal crash. Fix this by returning an error code if this case is triggered. Signed-off-by: Dinghao Liu --- drivers/ne
