net: add missing ref_tracker_dir_exit() to alloc_netdev_mqs()
sashiko is reporting that trying to read /sys/kernel/debug/ref_tracker/*
causes use-afer-free crash when either alloc_percpu() or dev_addr_init()
in alloc_netdev_mqs() failed, for commit 4d92b95ff2f9 ("net: add net device
refcount tracker infrastructure") added ref_tracker_dir_exit() to only
free_netdev() path.
