block, bfq: return nbytes and not zero from struct cftype .write() me…
…thod commit fc8ebd01deeb12728c83381f6ec923e4a192ffd3 upstream. The value that struct cftype .write() method returns is then directly returned to userspace as the value returned by write() syscall, so it should be the number of bytes actually written (or consumed) and not zero. Returning zero from write() syscall makes programs like /bin/echo or bash spin. Signed-off-by: Maciej S.
