Fix the issue in DIV_ROUND_CLOSEST implementation. Current
implementation will have issues for an input of two negative
numbers. For example, Input values of a = -13 and divisor = -5
should ideally give result as 3. But because of the third condition
check ie.(val) > 0, the result would be given incorrectly as 2
with the current implementation. Modify the condition to handle
two negative number division.

(which should not used for QNX code). This file was used for
compiling linux userspace driver("libnvgpu-drv.so") and was used for

- For QNX driver, "nvgpu_rmos/trace/events/gk20a.h" was used.

The atomic counter in interrupt handler can overflow and result in
calling of BUG() which will crash the process. The equivalent
functionality can be implemented with just setting an atomic variable at
start of handler and resetting at end of handler. The wait can be longer
in case there is constant interrupts coming but ultimately it will end.
Generally the wait path is not time critical so it should not be an
issue. Also, fix the unit tests for mc.

Update SW quiesce as follows:
- After waking up sw_quiesce_thread, nvgpu_sw_quiesce
masks interrupts, then disables and preempts runlists
without lock. There could be still a concurrent thread
that would re-enable the runlist by accident. This is
very unlikely and would mean we are not in mission mode
anyway.
- In sw_quiesce_thread, wait NVGPU_SW_QUIESCE_TIMEOUT_MS,
to leave some time for interrupt handler to set error
notifier (in case of HW error interrupt). Then disable
and preempt runlists, and set error notifier for remaining
channels before exiting the process.
Also modified nvgpu_can_busy to return false in case
SW quiesce is pending. This will make subsequent
devctl to fail.
