drm: Free devname along with master->unique
The device name is tightly coupled and created at the same time as the
master->unique address, so we need to free it with the master. Currently
we overwrite it each time we create a new master:
unreferenced object 0xe32c54b0 (size 32):
comm "Xorg", pid 1455, jiffies 4294721798 (age 3196.879s)
hex dump (first 32 bytes):
69 39 31 35 40 70 63 69 3a 30 30 30 30 3a 30 30 i915@pci:0000:00
