usb: usbtmc: uninitialized symbol 'actual' in usbtmc_ioctl_clear
[ Upstream commit 9a83190300867fb024d53f47c31088e34188efc1 ]
Fix uninitialized symbol 'actual' in function usbtmc_ioctl_clear.
When symbol 'actual' is not initialized and usb_bulk_msg() fails,
the subsequent kernel debug message shows a random value.
