In sd_setup_discard_cmnd() there are a some discard
methods that fall back to using WRITE_SAME. It
appears that those paths using WRITE_SAME should
also use the SD_WRITE_SAME_TIMEOUT instead of the
default SD_TIMEOUT.

I don't have a use case that breaks the current code.
It just seems to me that setups for discard and
write same should be consistent.
