NFSD: fix use-after-free in nfsd4_ssc_setup_dul()
[ Upstream commit e6cf91b7b47ff82b624bdfe2fdcde32bb52e71dd ]
If signal_pending() returns true, schedule_timeout() will not be executed,
causing the waiting task to remain in the wait queue.
Fixed by adding a call to finish_wait(), which ensures that the waiting
task will always be removed from the wait queue.
Fixes: f4e44b393389 ("NFSD: delay unmount source's export after inter-server copy completed.")
