CVS commit: src/sys/dev/sdmmc
Module Name: src
Committed By: jakllsch

If we get a SDMA boundary-crossing interrupt at the end of the final
segment, the transfer is not implicitly complete; we still need to wait
for the transfer complete interrupt so that we can issue new commands
This fixes the problem my Ricoh R5C822 was having where all writes after
a larger (64KiB) write were failing because we attempted to issue CMD13
(to check the status of the aformentioned write) too soon afterwards.
I suspect this fix to apply to other Ricoh SDHCI controllers I've heard
people have had trouble with. Sorry I didn't look at this sooner.
