Don't retry downloads when disk is full

Browse source 
There was already a check that prevented protocol-level fallback in this
situation, but retries within a specific protocol will still happen.
This makes it take a long time for the pull to finally error out.

This fixes slowness in TestDaemonNoSpaceleftOnDeviceError, which used to
take a long time due to the backoff between retry attempts:

PASS: docker_cli_daemon_test.go:1868: DockerDaemonSuite.TestDaemonNoSpaceleftOnDeviceError	5.882s
