    process: Fix disconnect when BB_SERVER_TIMEOUT
    
    Fixed:
    $ export BB_SERVER_TIMEOUT=10000
    $ bitbake --server-only
    $ bitbake --status-only
    [snip]
      File "/buildarea/lyang1/poky/bitbake/lib/bb/server/process.py", line 472, in recvfds
        msg, ancdata, flags, addr = sock.recvmsg(1, socket.CMSG_LEN(bytes_size))
    OSError: [Errno 9] Bad file descriptor
    
    And:
    $ export BB_SERVER_TIMEOUT=10000
    $ bitbake --server-only -B localhost:-1
    $ bitbake --status-only # Everything is fine in first run
    $ bitbake --status-only
    [snip]
      File "/buildarea/lyang1/poky/bitbake/lib/bb/server/process.py", line 472, in recvfds
        msg, ancdata, flags, addr = sock.recvmsg(1, socket.CMSG_LEN(bytes_size))
    OSError: [Errno 9] Bad file descriptor
    
    This was because self.controllersock was not set to False, so it still ran
    sock.recvmsg() when sock was closed.
    
    And also need set command_channel to Flase, otherwise the
    self.command_channel.get() will always run when EOF, and cause infinite loop.
