[PATCH master] device: use free_const to free device/bobject name

[Sascha Hauer <s.hauer@pengutronix.de>]

A device name (and thus a bobject name) may be statically allocated. Use
free_const() to handle this gracefully.

bobject_set_name() called from dev_set_name() also assumes that
dev->name is allocated and frees the existing name. Use free_const()
here as well.

Fixes: 1e91e857bf ("bobject: free object name in bobject_del()")
