Subject: [PATCH v3] staging: android: Clean up else statement from
 binder_send_failed_reply

Kernel coding style. Remove useless else statement after return.
Changes from v1 and v2: Fix warning for mixed declarations and code.
Declaration of "struct binder_transaction *next" made outside of while,
and initialized with NULL.
