-rename err() function to avoid clashing with err() form C library
-
-err() is a function available in the C library, so when static linking,
-there is a clash at link timebecause the function is provided both by
-nbd and the C library:
-    http://autobuild.buildroot.org/results/aa8/aa8a1ac35a93e1c8b9fddbc2b5d66ecaa921f31e/build-end.log
-
-Fix that by renaming err() to nbd_err() and providing a small maco
-wrapper to avoid touching the many call sites.
