afr: remove memcpy of @local contents in afr_local_copy
copy out members which are needed. memcpy of full local causes a copy of pointers without references and results in various corruption errors Signed-off-by: Anand V. Avati <avati@blackhole.gluster.com> Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 170 (Auto-heal fails on files that are open()-ed/mmap()-ed) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=170
