Removal of whole device check

Making a filesystem with a raw block device will semi-randomly prompt asking if we are sure. This is because `check_plausibility()` assumes that the Linux device numbering code assumes that raw block devices are assigned minor versions that are 0 modulo 64, when modern Linux systems are 0 modulo 16.

A patch was submitted to upstream yesterday. It has signed-off from myself and  reviewed-by from Andreas Dilger:

http://article.gmane.org/gmane.comp.file-systems.ext4/48840

HEAD moved the code that needs to be patched from misc/util.c to misc/plausibility.c, so the upstream patch does not apply to distribution packaging. I have taken the liberty of attaching a backported version of the patch.

I realize that upstream has not had time to process this yet, but my collegues insisted that I file issues with major distributions to request this patch be backported anyway. If I should have waited for a solution to be merged upstream, please let me know so that I can pass that information on to my collegues.

unless it's a critical issue, or there's another revbump coming up (i don't think there is?), then i'd just wait for the next release
