fix two places that need to check for an error return from nfsrv_getattrbits
nfsrv_getattrbits() can return an error when the
received attribute bitmap does not parse correctly.
There were two places in the client where the code
did not check for such an error return.
This patch fixes these two cases and should fix the
crashes.
Maybe the reporter can confirm that the patch stops the
crashes for them?
