memstick: use sector_div instead of do_div
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/memstick/core/ms_block.c: In function 'msb_io_work':
include/asm-generic/div64.h:207:28: warning: comparison of distinct pointer types lacks a cast
This changes the code to use sector_div instead, which always produces
optimal code.
