fx2lafw: Fix segfault wrt libusb_detach_kernel_driver().

Move the libusb_detach_kernel_driver() call after the code that
sets the usb->devhdl pointer, otherwise it'll be NULL and result
in a segfault.

  #0  libusb_kernel_driver_active (dev=0x0, interface_number=0) at libusb/core.c:1711
  #1  dev_open (sdi=0x12d99f0) at src/hardware/fx2lafw/api.c:374
  [...]

Tested on a device with the default Cypress VID/PID and one with
the Saleae Logic VID/PID, both works fine.
