afr: send unique dict_t instances to replicas in self-heal fxattrop

afr_sh_data_fxattrop() currently allocates and sends a single xattr
dict_t instance to each replica. The callback codepath references
the returned object in the self-heal in-memory state for the
particular replica. If storage/posix is in the same address-space
(i.e., running a single glusterfs client with a fuse->afr->posix
graph), the same object is modified and returned for each child,
causing corrupted in-memory state and afr xattrs.

Allocate and send independent xattr dict_t's for each replica. This
allows self-heal to work correctly in a single address-space
graph.
