usb: misc: uss720: fix uninitialized variable rlen
Smatch reports the following error: uninitialized symbol 'rlen'
drivers/usb/misc/uss720.c:514 parport_uss720_epp_write_data() error
drivers/usb/misc/uss720.c:575 parport_uss720_ecp_write_data() error
drivers/usb/misc/uss720.c:593 parport_uss720_ecp_read_data() error
drivers/usb/misc/uss720.c:626 parport_uss720_write_compat() error
The root cause is, the failure of usb_bulk_msg leads to the
uninitialized variable rlen in printk function.
Fix this by initializing rlen with zero.
