net: dsa: b53: check for timeout
clang static analysis reports this problem b53_common.c:1583:13: warning: The left expression of the compound assignment is an uninitialized value. The computed value will also be garbage ent.port &= ~BIT(port); ~~~~~~~~ ^ ent is set by a successful call to b53_arl_read(). Unsuccessful calls are caught by an switch statement handling specific returns. b32_arl_read() calls b53_arl_op_wait() which fails with the unhandled -ETIMEDOUT. So add -ETIMEDOUT to the switch statement. Because b53_arl_op_wait() already prints out a message, do not add another one.
