adbd: limit the sizes of aio writes.
The kernel does a kmalloc of the write size for each write during
io_submit, which can lead to failure if the kernel's heap is fragmented
such that it can't allocate a contiguous 1MB chunk. Partition writes
into 16 page chunks which are much more likely to succeed.
