Increase the batch limit to consume small message bursts more
effectively. Practically, the effect on the 'add' messages is not
significant since the mailbox is sized such that the 'add' messages are
still limited to the same order of magnitude that it was originally set
for.
Furthermore, increase the queue size limit to 1024 entries. This further
improves the handling of bursts of small control messages.

We need to do our best not to drop delete commands, otherwise
we will have stale entries in the connection table. Ignore
the control message queue limits for delete commands.

Some control messages must be sent from atomic context. The mailbox
takes sleeping locks and uses a waitqueue so add a "posted" version
of communication.
Trylock the semaphore and if that's successful kick of the device
communication. The device communication will be completed from
a workqueue, which will also release the semaphore.
If locks are taken queue the message and return. Schedule a
different workqueue to take the semaphore and run the communication.
Note that the there are currently no atomic users which would actually
need the return value, so all replies to posted messages are just
freed.

FW may prefer to handle some communication via a mailbox
or the vNIC may simply not have a control queue (VFs).
Add a way of exchanging ccm-compatible messages via a
mailbox.
