LINSTOR satellite aborts resource initialization with "Device is held open
by someone" (errno -12) when an external probe (Talos block-controller,
udev, multipathd) opens the freshly-promoted DRBD device just before the
post-mkfs demotion. The controller view then stays in SyncTarget /
Inconsistent / DELETING indefinitely, blocking cleanup of orphan PVs in
Released phase.
Add a retry wrapper secondaryAfterMkfs() with exponential backoff
(7 attempts, 250ms -> 2s) that triggers only on this specific error
message. DrbdPrimary.close() now uses the wrapper so the retry only
applies to the post-mkfs demotion path; the existing public secondary()
contract is untouched.
