Four reports (drm and ip2main.c) were non-obvious and the
maintainers have been poked.
The ll_rw_blk.c change could be a little more elegant.
Really, we should propagate a failure of blk_init_queue()
all the way back to the caller. In this patch we simply
leave the device with a less-than-expected pool of requests
and just limp along. Seems to be better than crashing.
Patch is against -ac24.
