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.

The driver is using its struct usb_device pointer as an inverted
disconnected flag, but was setting it to NULL before making sure all
completion handlers had run. This could lead to a NULL-pointer
dereference in a number of dev_dbg and dev_err statements in the
completion handlers which relies on s
Make sure to check for short transfers when retrieving the version
information at probe to avoid leaking uninitialised slab data when
logging it.

This series fixes a few issues found in the legousbtower driver. The
potential deadlock issue was reported by syzbot, and the rest was found
through inspection.
I have bunch of clean ups for this driver as well that I'll post once
these are in Linus's tree.

Fix a potential deadlock if disconnect races with open.
Since commit d4ead16f50f9 ("USB: prevent char device open/deregister
race") core holds an rw-semaphore while open is called and when
releasing the minor number during deregistration. This can lead to an
ABBA deadlock if a driver takes a lock
