[PATCH 1/1] i3c: master: Fix missing 'ret' assignment in set_speed()

[Frank Li <Frank.Li@nxp.com>]

Fix a probe failure in the i3c master driver that occurs when no i3c
devices are connected to the bus.

The issue arises in `i3c_master_bus_init()` where the `ret` value is not
updated after calling `master->ops->set_speed()`. If no devices are
present, `ret` remains set to `I3C_ERROR_M2`, causing the code to
incorrectly proceed to `err_bus_cleanup`.
