thunderbolt: Initialize ->domain_released completion before it is being used
Both Woody and Marek reported following crash:
BUG: unable to handle page fault for address: fffffffffffffff8
Call Trace:
<TASK>
device_release+0x43/0x90
kobject_cleanup+0x3c/0x180
icm_probe+0x19c/0x550 [thunderbolt]
nhi_probe+0x1a4/0x370 [thunderbolt]
local_pci_probe+0x41/0x90
pci_call_probe+0x5b/0x1a0
...
This only triggers on the error path when icm_probe() fails and the
domain structure is released, it tries to complete() uninitialized
completion.
Fix this by initializing the completion earlier.
