The read callbacks for the fixed address clients, that don't have flow control are built now on the receive path. In order to have a single allocation place we remove the allocation from the read request.

The read callback is always prepared with MTU-sized buffer and the FW can't send more than the MTU in one message. Checking for buffer existence and krealloc to increase receive buffer size are redundant and may be safely discarded.

The Fixed address clients do not work with the flow control, and the packet RX callback was allocated upon TX with anticipation of a following RX. This won't work if the clients with unsolicited Rx. Rather than preparing read callback upon a write we allocate one directly on the reciev path if one doesn't exists.

In the course of the read flow we want to wait for read completion only if the read queue is empty. However the calling list_empty(&cl->rd_completed) is a duplication as the same check was performed by mei_cl_read_cb() and the waiting is skipped if it returns not NULL.

Currently, all requests cancelled by the user are immediately removed from the queues. Such removal can cause unexpected behavior in the case when a request is partially written or a reply is received after the request is cancelled. To resolve this a request is always fully processed and the result is discarded in case the request was canceled.
