[pull-request][utopic SRU] iwlwifi: Backport firmware monitor support

[Seth Forshee]

These patches were backported from 3.17 by Intel to help with debugging
firmware issues [1]. They aren't suitable for upstream stable, but Intel
wireless is widely used among Ubuntu users so I think it makes sense for
us to pick them up if it's going to help get firmware bugs fixed.

The firmware monitor support is disabled be default and enabled only
when the fw_monitor=1 option is given to iwlwifi. I have reviewed the
patches, and I believe they have low potential for regression,
especially without the module option. I also saw no regressions during
testing, with or without the module option.

Thanks,
Seth
