Previously, the shared buffer pools were allocated on the
nvmf controllers. When a new connection was established,
the CONNECT command needs a 4k buffer, but we didn't know
which nvmf controller it belonged to until after the
CONNECT command completed. So there was a special case
for CONNECT that used in capsule data buffers instead.
Now, the buffer pool is global and always available. We
can just use that always, with no more special cases.
This has the additional nice side effect of allowing
users to run the target with no in capsule data buffers
allocated at all.

From the exising code, the comparison should + 1.
Suppose offset = 2^19, we still can be fit into
tree with level =0, since there will be 64 buffer,
each with size 2^18, so we do not need to
increse the tree level.
Also a unit test is added to demonstrate this.
