USB: legousbtower: fix open after failed reset request
commit 0b074f6986751361ff442bc1127c1648567aa8d6 upstream.
The driver would return with a nonzero open count in case the reset
control request failed. This would prevent any further attempts to open
the char dev until the device was disconnected.
Fix this by incrementing the open count only on successful open.
