Duoming Zhou e6ad2311e0 ax25: Replace kfree() in ax25_dev_free() with ax25_dev_put()
[ Upstream commit 166fcf86cd34e15c7f383eda4642d7a212393008 ]

The object "ax25_dev" is managed by reference counting. Thus it should
not be directly released by kfree(), replace with ax25_dev_put().

Fixes: d01ffb9eee4a ("ax25: add refcount in ax25_dev to avoid UAF bugs")
