qcacmn: Set the CE2 buffer size to 3200 bytes

Buffers attached to CE2 destination ring are of 4k bytes.
skb allocation for these buffers exceed 1-page allocation
due to addition bytes reserved for alignment, padding and
skb shared info.

Set the CE2 buffer size to 3200 bytes so that the skb memory
fits into a single page.
