just UNLOCK on node.
(lf_setlock): Move ret definition where it's used. Drop unneeded
tests for obj being not NULL. Only check for deadlock condition if the
lock we're trying to establish is a POSIX lock. Revamp object
collecting and wait code to cover all cases. Don't return with EDEADLK
if blocking process can't be opened for synchronization in F_POSIX case,
rather just wait like in F_FLOCK case. Change system_printf to
debug_printf in that case. Only run WaitForMultipleObjects with high

need_fork_fixup only if call was successful. Handle EINTR and
ECANCELED return values from lf_setlock.
(lf_setlock): Drop WAIT_UNLOCKED and WAIT_PROC_EXITED. Don't wait
for event object handle count to become <= 1 in F_LOCK case.
Simplify WFMO return value handling. Don't handle signal and cancel
events here; just return with appropriate error code instead.
(lf_getblock): Ignore locks for which the handle can't be opened.
Use IsEventSignalled.
* ntdll.h (STATUS_INVALID_INFO_CLASS): Undef if defined elsewhere to
make sure the definition is casted to NTSTATUS.
