* Use a special format string specification for the desired output of the
array "pgid" into a sequence.
This issue was detected by using the Coccinelle software.
* Delete the local variable "j" and a call of the function "seq_puts"
wich became unnecessary with this refactoring.
Fixes: 5a3b7b112884f80ff19b18028fabeb4f9c035518 ("s390/dasd: add query host access to volume support")
