fs/affs/super.c: bugfix / double free
commit d353efd02357a74753cd45f367a2d3d357fd6904 upstream.
Commit 842a859db26b ("affs: use ->kill_sb() to simplify ->put_super()
and failure exits of ->mount()") adds .kill_sb which frees sbi but
doesn't remove sbi free in case of parse_options error causing double
free+random crash.
