tests/gem_pwrite_pread: subtest annotation

Browse Source 
This testcase mixes correctnes tests with performance tests, so it's
good to track the different correctness test separate for QA.

Together with pread_after_blt the pwrite->blt tests here exercise the
full cache coherency lifecycle of both snooped and uncached objects.

/me is happy
