We'll also need to deal with the blk-mq wait path that Bart has been
working on (I think it's already in the scsi tree, but I'd have to
check).

Also adding a bool flag for the last call in a function is style that's
a little annoying.

I'd prefer to add a scsi_internal_device_block_nowait that contains
all the code except for the waiting, and then make
scsi_internal_device_block_nowait a wrapper around it.  Or drop the
annoying internal for both while we're at it :)
