cluster/ec: Change handling of heal failure to avoid crash

Problem:
ec_getxattr_heal_cbk was called with NULL as second argument
in case heal was failing.
This function was dereferencing "cookie" argument which caused crash.

Solution:
Cookie is changed to carry the value that was supposed to be
stored in fop->data, so even in the case when fop is NULL in error
case, there won't be any NULL dereference.

Thanks to Xavi for the suggestion about the fix.
