The NULL pointer check was the only way for that function to fail. And it
was done after the pointer was accessed. Simplify this by just returning
the result as a return value instead of using a pointer as output
parameter. This way the function can never fail and the caller doesn't
need to do any error handling.
Declare the function in libhsakmt.h instead of duplicating the
declaration in fmm.c.

New queue suspend/resume update can now return the number of successful
queue requests so return success if IOCTL return is non-negative.
This should be backwards compatible since old queue suspend/resume returns
0 on success.

Child process hsaKmtOpenKFD() call must re-initialize global variables
copied from parent process. This includes close all file handles, free
dynamically malloc buf. Double free issue is because destroy_device_
debugging_memory() free the memory in parent process hsaKmtCloseKFD()
but don't reset it to null pointer. As a result, child process free it
again. kfd_fd is closed in parent process but don't reset to 0, so
child process close it again.
Fix: reset kfd_fd to 0 after close, reset is_device_debugged pointer to 0
after free

Use checkpatch.pl to fix the majority of errors. Some that remain and
will be excluded:
Use of typedefs/externs/volatile/sscanf
Lines over 80 characters
Remaining errors are due to misunderstanding the * symbol with typedefs
Also use this opportunity to spell manageable properly

This change breaks the ABI, and aligns it with the upstream ABI.
It also fixes some ioctl structures that are not 64-bit safe and
consolidates ioctl numbers.
