[PATCH] scsi: Remove warnings after vsprintf %pV introducation.

[David Miller <davem@xxxxxxxxxxxxx>]

GCC warns about empty printf format strings, and after
the addition of %pV these existing such cases in the
scsi driver layer were exposed enough for the compiler
to start seeing them.

Based almost entirely upon a patch by Joe Perches.
