fuse2fs: fix return value handling

For the xattr functions, don't obliterate the return value of the file
system operation with an error code coming from ext2fs_xattrs_close
failing.  Granted, it doesn't ever fail (right now!) so this is mostly
just preening.

Also fix the obsolete op_truncate not to squash error returns.
