gpu: nvgpu: handle misaligned_addr SM exception
We right now do not handle misaligned_addr SM exception explicitly and hence
we incorrectly initiate CILP on this exception
Handle this exception explicitly in this sequence -
- set error notifier first
- clear the interrupt
- return error from gr_gv11b_handle_warp_esr_error_misaligned_addr() so that
RC recovery is triggered by gk20a_gr_isr()
Ensure that the error value is propagated back to gk20a_gr_isr() correctly
Use nvgpu_set_error_notifier_if_empty() to set error notifier since this will
prevent overwriting of error notifier value in case gk20a_gr_isr() also tries
to write to some error notifier value
