net: systemport: Fix memleak in bcm_sysport_probe

Browse source 
[ Upstream commit 7ef1fc57301f3cef7201497aa27e89ccb91737fe ]

When devm_kcalloc() fails, dev should be freed just
like what we've done in the subsequent error paths.

Fixes: 7b78be48a8 ("net: systemport: Dynamically allocate number of TX rings")
