There was a discrepancy between what `ParseTCPAddr()` accepted, and what the
daemon was able to use, resulting in the daemon to start, but fail to create
listeners for the specified host.
Before this patch:
dockerd -H tcp://127.0.0.1:2375/
INFO[2022-04-03T10:18:06.417502600Z] Starting up
...
failed to load listeners: listen tcp: address tcp/2375/: unknown port
dockerd -H 127.0.0.1:2375/path

...
failed to load listeners: listen tcp: address tcp/5555/path: unknown port
After this patch:
dockerd -H tcp://127.0.0.1:2375/
Status: invalid argument "tcp://127.0.0.1:2375/" for "-H, --host" flag: invalid bind address (127.0.0.1:2375/): should not contain a path element
