Deepak Nibade 505b442551 gpu: nvgpu: acquire mutex for notifier read ...

We use &ch->error_notifier_mutex to protect
writes and free of error notifier
But we currently do not protect reading of
notifier in gk20a_fifo_set_ctx_mmu_error()
and vgpu_fifo_set_ctx_mmu_error()

Add new API gk20a_set_error_notifier_locked()
which is same as gk20a_set_error_notifier()
but without the locks.

In *_fifo_set_ctx_mmu_error() APIs, acquire
the mutex explicitly, and then use this new
API

gk20a_set_error_notifier() will now just call
gk20a_set_error_notifier_locked() within
a mutex
