i3c: dw: Fix use-after-free in dw_i3c_master driver due to race condition

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

i3c: dw: Fix use-after-free in dw_i3c_master driver due to race condition

In dw_i3c_common_probe, &master->hj_work is bound with

dw_i3c_hj_work. And dw_i3c_master_irq_handler can call

dw_i3c_master_irq_handle_ibis function to start the work.

If we remove the module which will call dw_i3c_common_remove to

make cleanup, it will free master->base through i3c_master_unregister

while the work mentioned above will be used. The sequence of operations

that may lead to a UAF bug is as follows:

CPU0 CPU1

| dw_i3c_hj_work

dw_i3c_common_remove |

i3c_master_unregister(&master->base) |

device_unregister(&master->dev) |

device_release |

//free master->base |

| i3c_master_do_daa(&master->base)

| //use master->base

Fix it by ensuring that the work is canceled before proceeding with

the cleanup in dw_i3c_common_remove.
