[GFS2] Fix sign problem in quota/statfs and cleanup _host structures
This patch fixes some sign issues which were accidentally introduced into the quota & statfs code during the endianess annotation process. Also included is a general clean up which moves all of the _host structures out of gfs2_ondisk.h (where they should not have been to start with) and into the places where they are actually used (often only one place). Also those _host structures which are not required any more are removed entirely (which is the eventual plan for all of them). The conversion routines from ondisk.c are also moved into the places where they are actually used, which for almost every one, was just one single place, so all those are now static functions. This also cleans up the end of gfs2_ondisk.h which no longer needs the #ifdef __KERNEL__. The net result is a reduction of about 100 lines of code, many functions now marked static plus the bug fixes as mentioned above. For good measure I ran the code through sparse after making these changes to check that there are no warnings generated. This fixes Red Hat bz #239686 Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
