This config option is to set max_dev in api_storage.c. IMHO, the use
of max_dev is a bit pointless. The get_dev function will return NULL
when there are no more devices. My plan to fix is by removing max_dev
usage altogether.

There also appears to be a bug in that more than 1 device of a given
type will never be enumerated. The problem is in dev_stor_get. When
first is set, then *more is always returned as 0.
