[ Upstream commit 4506f23e117161a20104c8fa04f33e1ca63c26af ]
Currently, if the OPEN compound experiencing an error and needs to get the file attributes separately, it will send a stand alone GETATTR but it would use the filehandle from the results of the OPEN compound. In case of the CLAIM_FH OPEN, nfs_openres's fh is zero value. That generate a GETATTR that's sent with a zero value filehandle, and results in the server returning an error.
Instead, for the CLAIM_FH OPEN, take the filehandle that was used in the PUTFH of the OPEN compound.
