Ludovic Desroches b8f4b96768 mmc: android-goldfish: fix bad logic of sg_copy_{from,to}_buffer conversion ...

[ Upstream commit 17e96d8516 ]

The conversion to sg_copy_{from,to}_buffer has been done in the wrong
way. sg_copy_to_buffer is a copy from an SG list to a linear buffer so
it can't replace memcpy(dest, host->virt_base, data->sg->length) where
dest is the virtual address of the SG. Same for sg_copy_from_buffer
but in the opposite way.
