Subject: [PATCH] dmaengine: pl08x: fix conversioin for generic unmap data

commit d38a8c622a1b ('dmaengine: prepare for generic 'unmap' data')
added a generic unmap call but used the wrong argument for it. Fix it.

I can't actually tell what the intent of d38a8cc622a1b and how mappings
are expected to be managed, but it's obviously passing the wrong thing
in here so it seems like the appropriate fix.
