This patch will fix the below compilation errors on i386 ARCH
drivers/built-in.o: In function `_scsih_qcmd':
mpt2sas_scsih.c:(.text+0x1e7b56): undefined reference to `__udivdi3'
mpt2sas_scsih.c:(.text+0x1e7b8a): undefined reference to `__umoddi3'
Used sector_div() API to fix above compilation errors.
