Hans de Goede 5ce524bdff scsi/sd: add a no_read_capacity_16 scsi_device flag 
I seem to have a knack for digging up buggy usb devices which don't work
with Linux, and I'm crazy enough to try to make them work.  So this time a
friend of mine asked me to get an mp4 player (an mp3 player which can play
videos on a small screen) to work with Linux.

It is based on the well known rockbox chipset for which we already have an
unusual devs entries to work around some of its bugs.  But this model
comes with an additional twist.

This model chokes on read_capacity_16 calls.  Now normally we don't make
those calls, but this model comes with an sdcard slot and when there is no
card in there (and shipped from the factory there is none), it reports a
size of 0.  However this time the programmers actually got the
read_capacity_10 response right!  So they substract one from the size as
stored internally in the mp3 player before reporting it back, resulting in
an answer of ...  0xffffffff sectors, causing sd.c to try a
read_capacity_16, on which the device crashes.

This patch adds a flag to scsi_device to indicate that a a device cannot
handle read_capacity_16, and when this flag is set if a device reports an
lba of 0xffffffff as answer to a read_capacity_10, assumes it tries to
report a size of 0.
