nvgpu_rc_pbdma_fault just checks for the id and id_type from struct
nvgpu_pbdma_status_info. These contain invalid values during chsw_load
and chsw_switch. This patch corrects the above bug by checking for the
chsw status and then loading the values for id and type.
The current code reads the pbdma_status info after clearing the
interrupt. Other interrupts can cause enough delay between clearing the
interrupt and pbdma switching the channel leading to invalid channel/tsg
ID. Correct that by reading the pbdma_status info register before
clearing of the pbdma interrupt to correctly read the context
information before the pbdma can switch out the context.

If CONFIG_NVGPU_CE is disabled, nvgpu right now does not even reset
the CE engines or initialize prod values.
This ultimately needs to be fixed by adding appropriate initialization
for CE engines even if CONFIG_NVGPU_CE is disabled.
For now, add the code to at least reset CE engines if CONFIG_NVGPU_CE
is disabled
