gfs2: fix O_SYNC write handling
In gfs2_file_write_iter, for direct writes, the error checking in the buffered
write fallback case is incomplete. This can cause inode write errors to go
undetected. Fix and clean up gfs2_file_write_iter along the way.
Based on a proposed fix by Christoph Hellwig <hch@lst.de>.
