[ Upstream commit 66282ec1cf004c09083c29cb5e49019037937bbd ]
Clients must be able to read a file in order to execute it, and for pNFS that means the client needs to be able to perform a LAYOUTGET on the file.
This behavior for executable-only files was added for OPEN in commit a043226bc140 "nfsd4: permit read opens of executable-only files".
This fixes up xfstests generic/126 on block/scsi layouts.
