gpu: nvgpu: make nvgpu_init_mutex return void
...
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.

gpu: nvgpu: add locked cond APIs for posix
...
locked cond APIs are better suited when we have to check/set multiple
conditions before doing wait/signal. This should be preferred for qnx as
we can avoid unnecessary atomics.

gpu: nvgpu: nvgpu_cond_signal to return void
...
MISRA Rule-17.7 requires the return value of all functions to be used.
Fix is either to use the return value or change the function to return
void. This patch changes nvgpu_cond_signal and nvgpu_cond_signal_interruptible
to return void since no callers were using the return value.
