Staging: dgnc: release the lock before testing for nullity
The refactoring intrduced in
c84a083b995b ("Staging: dgnc: Use goto for spinlock release before return")
inverts the order in which the lock is released and ld is tested for nullity.
This patch restores the execution flow.
Fixes: c84a083b995b ("Staging: dgnc: Use goto for spinlock release before return")
