[PATCH i-g-t] tests/intel/gem_exec_capture: Check for partial register captures

[John.C.Harrison at Intel.com]

From: John Harrison <John.C.Harrison at Intel.com>

If there is an error in the register list provided to GuC by the KMD
then GuC will refuse to capture the invalid entries. This is reported
as a 'partial-capture' when decoding the register state. Check for
this and flag it as an error.
