Sparse Warning Message Patches

Sparse Warning Message Patches

[Alex Elder]

What follows is a few series of patches that get rid of code
issues that lead to warnings from the sparse utility.

The first three patches address the warnings in the rbd, ceph
file system, and libceph code respectively.  After that, one
warning remains in libceph, and that is addressed by a series
of five patches which both address the underlying problem and
reorganized and clean up the surrounding code.  The last two
are meant to be combined into one before commit; they've been
posted as two separate patches to make them easier to review.
