Fix format errors in brick/iscsi LOG messages

Currently in cinder.brick.iscsi.iscs:LioADM.create_iscsi_target
The Log message for the exception is:
  LOG.error("%s" % e),

This rightfully results in:
  *** UnicodeError: UnicodeError(u'Message objects
      do not support str() because they may contain
      non-ascii characters. Please use unicode() or
      translate() instead.',)

In some cases this causes the Volume service to stop and
doesn't help a ton with debug. While looking at this also
noticed a number of other similar cases where invalid LOG
messages were set up.  Following the i8n guidelines here:
http://docs.openstack.org/developer/oslo.i18n/guidelines.html

Went ahead and cleaned the bulk of the LOG messages in this
file up to adhere to the guidelines as well as fixing the
UnicodeError described in the bug.
