efi_pstore: Add a format check for an existing variable name at erasing time
[Issue]
a format of variable name has been updated to type, id, count and ctime
to support holding multiple logs.
Format of current variable name
dump-type0-1-2-12345678
type:0
id:1
count:2
ctime:12345678
On the other hand, if an old variable name before being updated
remains, users can't erase it via /dev/pstore.
Format of old variable name
dump-type0-1-12345678
type:0
id:1
ctime:12345678
[Solution]
This patch add a format check for the old variable name in a erase callback to make it erasable.
