Since ACRN has the capability to reboot and reboot reason is available
in SOS, acrnprobe could detect the crash of acrn and SOS kernel.
List of added crash types:
1. ACRNCRASH - crashed in hypervisor, this detection depends on
files in /tmp/acrnlog_last(provided by acrnlog).
2. IPANIC - crashed in SOS kernel, this detection depends on
pstore.
3. SWWDT_IPANIC - crashed in SOS kernel and reboot reason is wdt.
4. HWWDT_UNHANDLE - only recognize reboot reason is global, there is no
further clues that it's a SOS kernel crash or a
hypervisor crash.
5. SWWDT_UNHANDLE - only recognize reboot reason is wdt, there is no
further clues that it's a SOS kernel crash or a
hypervisor crash.
6. UNKNOWN - only recognize reboot reason is warm, there is no
further clues that it's a SOS kernel crash or a
hypervisor crash.

This patch is to fix potential issues, which are reported by static
analysis tool, for acrnprobe.
Changes:
1. Check the return value of sender_id() and get_sender_by_name(),
since it could be -1 or NULL.
2. Remove the parameter len from create_event, take parameter path
as a NULL-terminated string as default.
3. Modify for_each_* functions to avoid overflow.
