wsgi: pep8 fixes

Signed-off-by: Tushar Gohad <tushar.gohad@intel.com>
Jakub, two arguments for this qualified references:
- readability
- have you ever tried to mock.patch() imported function?
And two against:
- verbosity
- speed penalty

module1.py, def get_errno...

module2.py
from module1 import get_errno
def function_using_errno...

test.py
import module1, module2

def test01():
  module1.get_errno = lambda: 'mock'
  function_using_errno() # will continue with default implementation
