Fix display error on screen

The previous patch was reverted and is replaced by this one.

Instead of dancing around with global flag telling if a subsys succeed
or not and write a error, let's try to initialize the subsystem each
time a display is requested and output an error occurs.

That makes the code a bit nicer and give the opportunity to fix the
problem at the system level (eg. mount debugfs) without restarting
powerdebug.
