sparse fixes

sparse fixes

[Christoph Hellwig]

Hi all,

the first patch changes how STATIC is defined for debug builds to
make sparse checks for debug builds work without a lot of noise.

The rest fixes up various trivial sparse warnings.  After that we
have 5 warnings left, out of one which is in the new scrube code
and looks serious.  I'll try to find some time to look into it.

[PATCH 1/8] xfs: always define STATIC to static noinline

[Christoph Hellwig]

Ever since we added the noinline tag there is no good reason to define
away the static for debug builds - we'll get just as good debug
information with our without it, so don't mess up sparse and other
checkers due to it.

gcc 5.4 (Ubuntu 16.04) complains about a missing initializer for sx.sc
here.  Seeing as we memset it immediately afterwards, I'll just remove
the whole init thing.
