Shaun Ruffell d7c0b0aba1 wctc4xxp: Prevent exhausting memory in firmware. 
If the host system sends to many packets to the DTE to process, the on-card
memory can be exhausted which will result in an out of memory alert. In commit
2ac2338247, the driver will halt all communication
with the card and request a reload if any alert is received.

Now the driver will silently drop any "burst" traffic that was sent to the
transcoder as opposed to expecting the firmware to do it. There is currently a
limit of 640 samples (80ms of audio) in flight to the firmware at any one time
allowed.
