c6c52f4a71 Fix FAILFAST for pass-through requests 
It seems that REQ_QUIET and REQ_FAILFAST flags were confused. We want
both printed information in the logs about backend devices IO faulires
and fail fast pass-through requests without extra retries. Setting
rq->retries along is not sufficient, because in the kernel code retries
and the FAILFAST bitfields control behavior of different kernel pieces,
so they need to be used together. For instance, blk_noretry_request()
has no idea about rq->retries.

80be46ae7b scst_targ: Avoid incorrect block size changes 
The scst_block_generic_dev_done() function parses the READ CAPACITY
response without checking whether the response buffer has been
initialized. This can lead to incorrect block size changes and also
to the following kernel warning:
