Fix the following MISRA rule violations in bitops unit,
MISRA Rule 10.1
MISRA Rule 10.3
MISRA Rule 10.4
MISRA Rule 11.8
MISRA Rule 21.2
Introduce nvgpu specific functions for bitops and bitmap operations
with unsigned integer as parameter for offset. OS specific type
conversions and handling of these inerfaces are taken care in the
respective OS files.

Restricted the os specific channel open only for kernel mode submit.
For linux, g->os_channel.open is just noop.
For QNX, nvgpu creates the sync point notifier thread for
job tracking. This job completion tracking is only required
for kernel mode submit. This sync point notifier thread
is not required for user mode submit.

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.

The vm object num_user_mapped_buffers was declared as an int. However,
it is an unsigned value. Being a signed value required a cast to
unsigned when calling nvgpu_big_zalloc() which causes a CERT-C INT31
violation. So, avoid the cast and use an unsigned type. And fix related
INT30 violations related to num_user_mapped_buffers as well.
To avoid introducing new MISRA/CERT-C violations, update the upstream
user of these changes, fifo/channel.c and make the equivalent uses of
this value, num_mapped_buffers a u32 as well.
