block/gluster: return correct error value

Upon error, gluster will call the aio callback function with a
ret value of -1, with errno set to the proper error value.  If
we set the acb->ret value to the return value in the callback,
that results in every error being EPERM (i.e. 1).  Instead, set
it to the proper error result.
