[Bug 1458228] [NEW] improve error "Device is not available: No such device" of hcitool scan

Sat May 23 19:34:32 UTC 2015

Public bug reported:

The feedback `Device is not available: No such device` of `hcitool scan`
is unhelpful and should be replaced with a feedback explaining the state
(at least which device isn't there) and instructions how fix it.
