isci: audit usage of BUG_ON macro in isci driver
Removes unnecessary usage of BUG_ON macro, excluding core directory. In some cases macro is unnecesary, check is done in caller function. In other cases macro is replaced by if construction with appropriate warning. Signed-off-by: Maciej Patelczyk <maciej.patelczyk@intel.com> [changed some survivable bug conditions to WARN_ONCE] Signed-off-by: Dan Williams <dan.j.williams@intel.com>
