[PATCH v1] common/cnxk: fix integer overflow

The expression flow_age->aging_poll_freq * NPC_AGE_WAIT_TIMEOUT_US is evaluated using 32 bit arithmetic. An integer overflow may occur when the value is too large to fit in 32 bits. This patch resolves this by casting flow_age->aging_poll_freq to 64 bit. Coverity issue: 428156 Fixes: a4878294318e
