json_validation.py: reference to undefined variable name

[SwooshyCueb]

This method in json_validation.py references an undefined variable name:

irods/scripts/irods/json_validation.py

Lines 99 to 105 in e4b4e8a

	def load_json_schema_from_web(schema_uri):
	try:
	response = requests.get(schema_uri, timeout=5)
	except NameError:
	six.reraise(IrodsError,
	IrodsError('WARNING: Validation failed for {0} -- requests not installed'.format(name)),
	sys.exc_info()[2])

Apparently it's been this way for at least eight years.
