[PATCH 1/2] nfs4lib: update do_getattr to use root_fh if no fh provided

[Tigran Mkrtchyan <tigran.mkrtchyan@desy.de>]

do_getattr(FATTR4_XX) is now equal to do_getattr(FATTR4_XX, root_fh)
The use_obj is updated to return putrootfh operation if file object
is not provided.

This looks like safe change as do_getattr(attr, None) was broken
(c.homedir variable never exist), thus was never used.
