usbip: synchronize event handler with sysfs code paths
Fuzzing uncovered race condition between sysfs code paths in usbip
drivers. Device connect/disconnect code paths initiated through
sysfs interface are prone to races if disconnect happens during
connect and vice versa.
Use sysfs_lock to synchronize event handler with sysfs paths
in usbip drivers.
