Dimitris Karakasilis 0e278a89f0 Don't let the mapping be nil when reading an empty file ...

e.g. when we first create it

because it throws this error:

```
panic: assignment to entry in nil map

goroutine 1 [running]:
github.com/kairos-io/kcrypt/pkg/partition_info.PartitionInfo.UpdateMapping({{0xa60325?, 0x18?}, 0x0?}, {0xc000302000?, 0x1?})
