[PATCH v2 2/3] nodedev: Mark device initialization complete even in case of an error

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

To speed up nodedev driver initialization, the device enumeration
is done in a separate thread. Once finished, the thread sets a
boolean variable that allows public APIs to be called (instead of
waiting for the thread to finish).

However, if there's an error in the device enumeration thread
then the control jumps over at the 'error' label and the boolean
is never set. This means, that any virNodeDev*() API is stuck
forever. Mark the initialization as complete (the thread is
quitting anyway) and let the APIs proceed.
