Add two new configuration knobs to control the behavior of smb_WriteData.

HKLM\SOFTWARE\OpenAFS\Client
  DWORD EnableSMBAsyncStore  (default: 1)
  DWORD SMBAsyncStoreSize    (default: 32K)

Instead of tying the async store size to either the chunksize (too large)
or the buffer block size (too small) provide an intermediate value that
can be independently controlled.

In the future it would be desireable for the async store size to be
dynamically determined based upon measurable characteristics of the
network.  In the meantime, 32KB is an acceptable performance compromise
that should work well on 1Gbit networks and low-speed cellular networks.
