staging: kpc2000: remove unnecessary assertions in kpc_dma_transfer

Browse Source 
In kpc_dma_transfer(), the assertion that priv is NULL and priv->ldev
is NULL, are never satisfied. The two callers of the function,
dereference the fields before the function is called. This patch
removes the two BUG_ON calls.
