Frank Li e726cb3d35 i3c: master: svc: fix random hot join failure since timeout error 
commit 9aaeef113c55248ecf3ab941c2e4460aaa8b8b9a upstream.

master side report:
  silvaco-i3c-master 44330000.i3c-master: Error condition: MSTATUS 0x020090c7, MERRWARN 0x00100000

BIT 20: TIMEOUT error
  The module has stalled too long in a frame. This happens when:
  - The TX FIFO or RX FIFO is not handled and the bus is stuck in the
middle of a message,
  - No STOP was issued and between messages,
  - IBI manual is used and no decision was made.
  The maximum stall period is 100 μs.

This can be considered as being just a warning as the system IRQ latency
can easily be greater than 100us.
