jfs: fix uninitialized waitqueue in transaction manager

In the Linux kernel, the following vulnerability has been resolved:

jfs: fix uninitialized waitqueue in transaction manager

The transaction manager initialization in txInit() was not properly
initializing TxBlock[0].waitor waitqueue, causing a crash when
txEnd(0) is called on read-only filesystems.

When a filesystem is mounted read-only, txBegin() returns tid=0 to
indicate no transaction. However, txEnd(0) still gets called and
tries to access TxBlock[0].waitor via tid_to_tblock(0), but this
waitqueue was never initialized because the initialization loop
started at index 1 instead of 0.

This causes a 'non-static key' lockdep warning and system crash:
  INFO: trying to register non-static key in txEnd

Fix by ensuring all transaction blocks including TxBlock[0] have
their waitqueues properly initialized during txInit().
