[PATCH] memstick: tifm_ms: use the correct DMA direction on removal

[Avi Weiss]

tifm_ms_issue_cmd() maps READ requests with DMA_FROM_DEVICE and
WRITE requests with DMA_TO_DEVICE. When a request is active during
removal, tifm_ms_remove() unmaps it using the opposite direction.

Use the original mapping direction when unmapping an active
request, matching the normal completion path.
