tune2fs: print error message when closing the fs fails

I encountered an I/O error on writing the superblock on a drive:

  ...
  pwrite64(3, ..., 114688, 97844727808) = 114688
  fsync(3) = -1 EIO (Input/output error)
  close(3) = 0
  ...

The error was silently ignored, only indicated by the exit value. Let's
print an error message.

The error message was taken from mke2fs in order to reuse the
translations.
