Subject: [PATCH v2 3/5] block/partitions/acorn: Remove redundant assignments

Get rid of redundant assignments to a variable slot from function
adfspart_check_ADFS. It is being assigned a value that is never read
as we are breaking out from the switch case and the function ends.

Reported by clang-tidy [deadcode.DeadStores]
