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].
