Luciano Coelho a500e469ea iwlwifi: mvm: clean net-detect info if device was reset during suspend
If the device is reset during suspend with net-detect enabled, we
leave the net-detect information dangling and this causes the next
suspend to fail with a warning:

To fix this, call the iwl_mvm_free_nd() function in case of any error
during resume.  Additionally, rename the "out_unlock" label to err to
make it clearer that it's only called in error conditions.
