crypto: crypto4xx - fix double-free in crypto4xx_destroy_sdr
commit 746c908c4d72e49068ab216c3926d2720d71a90d upstream.
This patch fixes a crash that can happen during probe
when the available dma memory is not enough (this can
happen if the crypto4xx is built as a module).
The descriptor window mapping would end up being free'd
twice, once in crypto4xx_build_pdr() and the second time
in crypto4xx_destroy_sdr().
Fixes: 5d59ad6eea82 ("crypto: crypto4xx - fix crypto4xx_build_pdr, crypto4xx_build_sdr leak")
