Andrew Jones 81e25896cc RISC-V: hwprobe: Fix vDSO SIGSEGV
[ Upstream commit e1c05b3bf8 ]

A hwprobe pair key is signed, but the hwprobe vDSO function was
only checking that the upper bound was valid. In order to help
avoid this type of problem in the future, and in anticipation of
this check becoming more complicated with sparse keys, introduce
and use a "key is valid" predicate function for the check.

Fixes: aa5af0aa90 ("RISC-V: Add hwprobe vDSO function and data")
