NFC: fix device-allocation error return
A recent change fixing NFC device allocation itself introduced an error-handling bug by returning an error pointer in case device-id allocation failed. This is clearly broken as the callers still expected NULL to be returned on errors as detected by Dan's static checker. Fix this up by returning NULL in the event that we've run out of memory when allocating a new device id. Note that the offending commit is marked for stable (3.8) so this fix needs to be backported along with it.
