drm/amdkfd: range check cp bad op exception interrupts
[ Upstream commit 0cac183b98d8a8c692c98e8dba37df15a9e9210d ]
Due to a CP interrupt bug, bad packet garbage exception codes are raised.
Do a range check so that the debugger and runtime do not receive garbage
codes.
Update the user api to guard exception code type checking as well.
