crypto: talitos - don't persistently map req_ctx->hw_context and req_ctx->buf

Browse source

Commit 49f9783b0c ("crypto: talitos - do hw_context DMA mapping
outside the requests") introduced a persistent dma mapping of
req_ctx->hw_context
Commit 37b5e8897e ("crypto: talitos - chain in buffered data for ahash
on SEC1") introduced a persistent dma mapping of req_ctx->buf

As there is no destructor for req_ctx (the request context), the
associated dma handlers where set in ctx (the tfm context). This is
wrong as several hash operations can run with the same ctx.

This patch removes this persistent mapping.
