camcontrol: Bump timeout to get size of drive

When the system is very busy, and the ATA hard disk drives are
overloaded due to reading dodgy sectors, it can take several seconds to
drain the NCQ set of commands to send this command to the drive. Up the
timeout from 5s to 10s out of an abundance of caution, but also to allow
monitioring software that uses camcontrol identify to not fail
needlessly.
