can: peak_usb: fix mem leak in pcan_usb_pro_init()



This patch fixes a memory leak in pcan_usb_pro_init(). In patch

    f14e2243 net: can: peak_usb: Do not do dma on the stack

the struct pcan_usb_pro_fwinfo *fi and struct pcan_usb_pro_blinfo *bi were
converted from stack to dynamic allocation va kmalloc(). However the
corresponding kfree() was not introduced.

This patch adds the missing kfree().
