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.

Changes from v3: Removed initialization to NULL for next variable.
