gpu: nvgpu: make nvgpu_init_mutex return void

Browse Source 
Make the nvgpu_init_mutex function return void.
In linux case, this doesn't affect anything since mutex_init
returns void.
For posix, we assert() and die if pthread_mutex_init fails.

This alleviates the need to error inject for _every_
nvgpu_mutex_init function in the driver.
