selftests: netdevsim: Always initialize 'RET' variable
The variable is used by log_test() to check if the test case completely successfully or not. In case it is not initialized at the start of a test case, it is possible for the test case to fail despite not encountering any errors. Example: ``` ... TEST: Trap group statistics [ OK ] TEST: Trap policer [FAIL] Policer drop counter was not incremented TEST: Trap policer binding [FAIL] Policer drop counter was not incremented ``` Failure of trap_policer_test() caused trap_policer_bind_test() to fail as well. Fix by adding missing initialization of the variable.
