Linux: Fix set_cr_group_info and cr_group_info

Linux: Fix set_cr_group_info and cr_group_info

Commit dc85abca renamed set_cr_group_info to afs_set_cr_group_info
and cr_group_info to afs_cr_group_info, but didn't catch all call
sites. In particular, those in the NFS translator, in non-keyring
code paths, and in the 2.4 code, were missed.

Thanks to Adam Megacz for the bug report on openafs-info.
