[0/2] vb2: remove VB2_BUF_STATE_REQUEUEING

Message

The VB2_BUF_STATE_REQUEUEING leads to unordered behavior in vb2.
The only driver that used it was the cobalt driver, and replacing
VB2_BUF_STATE_REQUEUEING by VB2_BUF_STATE_ERROR is sufficient.

In addition, VB2_BUF_STATE_REQUEUEING can't be used with the Request
API, so removing support for this state altogether simplifies matters.

Regards,

	Hans
