+++ This bug was initially created as a clone of Bug #1648687 +++

Description of problem:

afr_open() stores fd reference in local->cont.open structure. But in the
callback function "afr_open_ftruncate_cbk" ( when openflags contain 'O_TRUNC'
set), we reference local->fd in AFR_STACK_UNWIND resulting in error or crash.
