[PATCH 2/2] bitbake: fetch2/wget: checkstatus: use the same arguments as parent

[Nicola Lunghi <nick83ola@gmail.com>]

the commit:
  312f1a5e741: bitbake: fetchption: attempt checkstatus again if it fails

was introducing an extra parameter to the checkstatus function, overriding
the parent.

Avoid that and remove recursion as is not needed.
Also introduce a small delay between the two requests.
