[PATCH] ext3: Wrong return value for EXT3_IOC_GROUP_ADD

This patch corrects the return value for the EXT3_IOC_GROUP_ADD in case it
fails due to the presence of multiple resizers at the filesystem.

The problem is a little bit more serious than a wrong return value in this
case, since the clause err=0 in the exit_journal path will lead to a call
to update_backups which in turns causes a NULL pointer dereference.
