jfs: turn diLog(), dataLog() and txLog() into void functions
These functions always return '0' and no callers use the return value. So make it a void function. This eliminates the following coccicheck warning: ./fs/jfs/jfs_txnmgr.c:1365:5-7: Unneeded variable: "rc". Return "0" on line 1414 ./fs/jfs/jfs_txnmgr.c:1422:5-7: Unneeded variable: "rc". Return "0" on line 1527 Reported-by: Abaci Robot <abaci@linux.alibaba.com> Signed-off-by: Yang Li <yang.lee@linux.alibaba.com> Signed-off-by: Dave Kleikamp <dave.kleikamp@oracle.com>
