13:51:57 2021 +0200 loop: Fix missing discard support when using LOOP_CONFIGURE Without calling loop_config_discard() the discard flag and parameters aren't set/updated for the loop device and worst-case they could indicate discard support when it isn't the case (ex: if the LOOP_SET_STATUS ioctl was used with a different file prior to LOOP_CONFIGURE).
