usb/usbip: fix wrong data added to platform device
.data of platform_device_info will be copied into .platform_data of
struct device via platform_device_add_data.
However, vhcis[i] contains a spinlock, is dynamically allocated and
used by other code, so it is not meant to be copied. The workaround
was to use void *vhci as an agent, but it was removed in the commit
suggested below.
This patch adds back the workaround and changes the way of using
platform_data accordingly.
