lib: Cache static queries

We frequently check for device capabilities, for which we can safely
assume that there is but one on a system and so cache the first query
value and return it for all future queries. The benefit is to reduce
dmesg debug spam which helps when either bringing up a test or trying to
track down why a test fails.
