hv_balloon: Remove redundant assignment to region_start
Variable region_start is set to pg_start but this value is never read as it is overwritten later on, hence it is a redundant assignment and can be removed. Cleans up the following clang-analyzer warning: drivers/hv/hv_balloon.c:1013:3: warning: Value stored to 'region_start' is never read [clang-analyzer-deadcode.DeadStores].
