kernel: USB: serial: cypress_m8: fix memory corruption with small endpoint

A flaw was found in the Linux kernel's cypressm8 USB serial driver. A malicious Universal Serial Bus USB device could report a packet size smaller than eight bytes for the interrupt-out endpoint. This can lead to memory corruption, specifically user-controlled slab corruption or a NULL-pointer...
