If MMP is enabled and e2fsck determines that it needs to restart itself on
account of various MMP conditions, it will close the current fs and jump back
to the start of fs checking. However, closing fs also frees it, which means
that we need to set ctx->fs to NULL to prevent subsequent open code from
accessing the old deleted pointer.
(This fix came up while testing the metadata checksumming patchset)
