usbip: cap iso packet count at linux USBIP_MAX_ISO_PACKETS

Browse source 
The accepted limit of 4096 was looser than Linux's hard cap of 1024 in
drivers/usb/usbip/usbip_common.h, so a real peer would reject submits we
considered valid. Tighten the validator to 1024 to match upstream before
multi-packet iso lands.
