Avihai Horon 3205bebd4f migration: Fix logic of channels and transport compatibility check 
The commit in the fixes line mistakenly modified the channels and
transport compatibility check logic so it now checks multi-channel
support only for socket transport type.

Thus, running multifd migration using a transport other than socket that
is incompatible with multi-channels (such as "exec") would lead to a
segmentation fault instead of an error message.
For example:
  (qemu) migrate_set_capability multifd on
  (qemu) migrate -d "exec:cat > /tmp/vm_state"
  Segmentation fault (core dumped)

Fix it by checking multi-channel compatibility for all transport types.
