afs: Remove erroneous seq |= 1 in volume lookup loop
The `seq |= 1` operation in the volume lookup loop is incorrect because:
seq is already incremented at start, making it odd in next iteration
which triggers lock, but The `|= 1` operation causes seq to be even
and unintended lockless operation
Remove this erroneous operation to maintain proper lock sequencing.
