PNP: fix name memory leak in pnp_alloc_dev() 

[ Upstream commit 110d7b0325 ]

After commit 1fa5ae857b ("driver core: get rid of struct device's
bus_id string array"), the name of device is allocated dynamically,
move dev_set_name() after pnp_add_id() to avoid memory leak.

Fixes: 1fa5ae857b ("driver core: get rid of struct device's bus_id string array")
