[PATCH] separate routine to check jffs2_flash_read

[Pierre.Ricadat@UTBM.fr]

Hi all'

here i attach a small patch for that 'todo' in nodelist.c:

  /* TODO: this is very frequent pattern, make it a separate
		   * routine */
  err = jffs2_flash_read(c, ofs, len, &retlen, buffer);
  ...

about the checking of jffs2_flash_read().

I made a new function : jffs2_check_flash_read to
- check that jffs2_flash_read returns success
- check that it read all
and in a case of failure, print error, free the buffer and return error code.
