test: proceed if timer subsystem already initialized

[ upstream commit 3dd7d69 ]

rte_timer_subsystem_init() may return -EALREADY if the timer subsystem
was already initialized. This can happen i.e. in PMD code (see
eth_ena_dev_init). This is not an error, rather a notification as the
initialization function simply returns without any action taken.

Fixes: 50247fe ("test/timer: exercise new APIs in secondary process")
