i3c: mipi-i3c-hci: Mask ring interrupts before ring stop request

CVE-2024-45828

Description

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

i3c: mipi-i3c-hci: Mask ring interrupts before ring stop request

Bus cleanup path in DMA mode may trigger a RING_OP_STAT interrupt when the ring is being stopped. Depending on timing between ring stop request completion, interrupt handler removal and code execution this may lead to a NULL pointer dereference in hci_dma_irq_handler() if it gets to run after the io_data pointer is set to NULL in hci_dma_cleanup().

Prevent this my masking the ring interrupts before ring stop request.
