Subject: [PATCH] e2fsck: free ctx->fs, not fs, at the end of fsck

When we call ext2fs_close_free at the end of main(), we need to supply
the address of ctx->fs, because the subsequent e2fsck_free_context
call will try to access ctx->fs (which is now set to a freed block) to
see if it should free the directory block list.  This is clearly not
desirable, so fix the problem.
