build: the main glusterfs package should not provide glusterfs-libs

Because of this incorrect provides, there is no requirement to update
glusterfs-libs. Most users will get a newer glusterfs-libs when updating
anyway, but users that manually select RPMs for updating my skip the
package, which will break their system.

cluster/dht: Make sure loc has gfid

Problem:
In some code paths neither loc->gfid nor loc->inode->gfid
is populated which leads to EINVAL for linkfile setattr
in dht_linkfile_attr_heal.

Fix:
Populate loc->gfid before dht_linkfile_attr_heal.
