do_div is the wrong way to divide a sector_t, as it is less
efficient when sector_t is 32-bit wide. With the upcoming
do_div optimizations, the kernel starts warning about this:
drivers/infiniband/ulp/iser/iser_verbs.c:1296:4: note: in expansion of macro
'do_div'
include/asm-generic/div64.h:224:22: warning: passing argument 1 of '__div64_32'
from incompatible pointer type
This changes the code to use sector_div instead, which always
produces optimal code.
