ALSA: caiaq: Allow zero-length packet handling for EP1
The recent fix to avoid OOB access for malformed packets added a
packet length check and returns immediately if it's too short.
However, this can be lead to a regression because the completion
handler doesn't resubmit the packet, while a zero-length packet itself
is valid, per se.
For addressing the potential regression above, change the handling for
a zero-length packet to just resubmit without processing the incoming
contents.
