lockd: remove redundant check on block

A null check followed by a return is being performed already, so block is always non-null at the second check on block, hence we can remove this redundant null-check (Detected by PVS-Studio). Also re-work comment to clean up a check-patch warning. Signed-off-by: Colin Ian King <[email protected]> Signed-off-by: J. Bruce Fields <[email protected]>
