efi_pstore: Remove a logic erasing entries from a write callback to hold multiple logs
[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 removes a logic erasing existing entries in a write callback because the logic is not needed in the write callback to support holding multiple logs.
