Review Comment:
   It's because the default value of max_conns is 0 
(https://github.com/apache/nuttx/blob/master/net/bluetooth/Kconfig#L57) and I 
found it means no limit because everywhere we use it to limit connections is 
checking `#if max_conns > 0`. In this PR I set the `sem` to `INT16_MAX` in 
`net_bufpool_init` to get similar behavior.
