soc: qcom: geni-se: Widen fw_size to u32 to prevent wrap-around

fw_size is read from the 16-bit fw_size_in_items field and incremented
when the count is odd. If fw_size_in_items == 0xffff the increment
wraps to 0 as a u16, making the bounds check below pass for a firmware
segment whose actual size was not validated. Widen fw_size to u32 so
the increment never wraps.
