This patch fixes the following memory leak reported by kmemleak:
unreferenced object 0xffff880060a53840 (size 192):
comm "softirq", pid 0, jiffies 4320571771 (age 1406.569s)
hex dump (first 32 bytes):
01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................

The problem is that when inc_tx() returns non-zero, we forgot
to call usb_free_urb().
