include/linux/byteorder/generic.h: fix index variables
In cpu_to_be32_array() and be32_to_cpu_array() the length of the array is
given by variable len of type size_t. An index variable of type int is used
to iterate over the array. This is bound to fail for len > INT_MAX and
lets GCC add instructions for sign extension.
Correct the type of the index variable.
