asm-generic/div64: Fix documentation of do_div() parameter 

Contrary to the description, the first parameter (n) should not be passed
as a pointer, but directly as an lvalue. This is possible because do_div() is
a macro.

/**
* do_div - returns 2 values: calculate remainder and update new dividend
* @n: pointer to uint64_t dividend (will be updated)
* @n: uint64_t dividend (will be updated)
* @base: uint32_t divisor
*
* Summary:
* ``uint32_t remainder = *n % base;``
* ``*n = *n / base;``
* ``uint32_t remainder = n % base;``
* ``n = n / base;``
*
* Return: (uint32_t)remainder
