Variable pg_size is set to '0x100 << pg_size', but this value is
never read as it is not used later on, hence it is a redundant
assignment and can be removed.

Clean up the following clang-analyzer warning:

drivers/target/sbp/sbp_target.c:1264:3: warning: Value stored to
'pg_size' is never read [clang-analyzer-deadcode.DeadStores].
