[MaxYaremchuk]

Description
The show interfaces status command returns traceback in case of adding a nonexistent port to a PortChannel

Moreover, In case of removing nonexistent port from portchannel teamd container gets rebooted.

Steps to reproduce the issue

1. create a portchannel : # config portchannel add PortChannel0001
2. Add a nonexistent interface to PortChannel0001: # config portchannel member add PortChannel0001 Ethernet128

Pay attention, interface Ethernet128 is nonexistent in the system.

3. Issue the command: show interfaces status

Describe the results you received
The system returns traceback:

Traceback (most recent call last):
  File "/usr/bin/intfutil", line 529, in <module>
    main(sys.argv[1:])
  File "/usr/bin/intfutil", line 522, in main
    interface_stat = IntfStatus(intf_name)
  File "/usr/bin/intfutil", line 443, in __init__
    self.portchannel_speed_dict = po_speed_dict(self.po_int_dict, self.appl_db)
  File "/usr/bin/intfutil", line 274, in po_speed_dict
    interface_speed = '{}G'.format(interface_speed[:-3])

4. Having removed a nonexistent port from portchannel # config portchannel member del PortChannel0001 Ethernet128
   teamd container got rebooted with errors in syslog:

Describe the results you expected
The config portchannel member add command should prevent from assigning to a portchannel nonexistent interface.
