[Spice-devel] [usbredir PATCH 4/6] usbredirhost: add LIBUSB_CALL to libusb complete-callback-functions

[Uri Lublin]

In libusb.h the following definition appears:
typedef void (LIBUSB_CALL *libusb_transfer_cb_fn)(struct libusb_transfer *transfer);

Added LIBUSB_CALL to the following functions:
	usbredirhost_iso_packet_complete
	usbredirhost_interrupt_packet_complete
	usbredirhost_control_packet_complete
	usbredirhost_bulk_packet_complete

This fixes the following compiler warning for Windows (mingw):
./usbredirhost/usbredirhost.c: In function 'usbredirhost_alloc_iso_stream':
./usbredir/usbredirhost/usbredirhost.c:1206:13: warning: passing argument 7 of 'libusb_fill_iso_transfer' from incompatible pointer type [enabled by default]
