power: supply: qcom_battmgr: remove bogus do_div()

The argument to do_div() is a 32-bit integer, and it was read from a
32-bit register so there is no point in doing a 64-bit division on it.

On 32-bit arm, do_div() causes a compile-time warning here:

    include/asm-generic/div64.h:238:22: error: passing argument 1 of '__div64_32' from incompatible pointer type [-Werror=incompatible-pointer-types]
