Log Message:
dk_start(): retry device-dependent start() routine later, also when it
returns ENOMEM in addition to EAGAIN.

Device-dependent start() routine may allocate buffer directly, or via
bus_dma(9) API (some implementations for bus_dma(9) like alpha allocate
memory internally).

If these attempts fail with ENOMEM, this is not a disk error, therefore
we must retry later, as already done for EAGAIN.
