[Issue] Currently, efi_pstore driver simply overwrites existing panic messages in NVRAM. So, in the following scenario, we will lose 1st panic messages. 1. kernel panics. 2. efi_pstore is kicked and writes panic messages to NVRAM. 3. system reboots. 4. kernel panics again before a user checks the 1st panic messages in NVRAM. [Solution] A reasonable solution to fix the issue is just holding multiple logs without erasing existing entries. This patch freshly adds a logic erasing existing entries, which shared with a write callback, to an erase callback. To support holding multiple logs, the write callback doesn't need to erase any entries and it will be removed in a subsequent patch.
