USB: serial: cypress_m8: fix interrupt-out transfer length
[ Upstream commit 56445eef55cb5904096fed7a73cf87b755dfffc7 ]
Fix interrupt-out transfer length which was being set to the
transfer-buffer length rather than the size of the outgoing packet.
Note that no slab data was leaked as the whole transfer buffer is always
cleared before each transfer.
Fixes: 9aa8dae7b1fa ("cypress_m8: use usb_fill_int_urb where appropriate")
