skadamati e768e74df8 gpu: nvgpu: Fix race condition during poweron ...

When two or more apps ran simultaneously
First app context sets power_on flag & starts init
Other app context check the power_on flag
and try to use GPU without init completed
Which makes aother apps to assert

Added mutex to synchronize poweron access
