Shuah Khan f06cb4641b usbip: synchronize event handler with sysfs code paths 
commit 363eaa3a450abb4e63bd6e3ad79d1f7a0f717814 upstream.

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.
