i40e: fix MMIO write access to an invalid page in i40e_clear_hw
In the Linux kernel, the following vulnerability has been resolved: i40e: fix MMIO write access to an invalid page in i40e_clear_hw When the device sends a specific input, an integer underflow can occur, leading to MMIO write access to an invalid page. Prevent the integer underflow by changing the type of related variables.
