i2c: designware-platdrv: fix cleanup on probe failure

Simplify the error handling in dw_i2c_plat_probe() by consolidating
cleanup operations directly in the error path instead of using a
goto label.

This eliminates the goto statement, makes the error handling more
transparent, and reduces code indirection while maintaining identical
cleanup behavior on probe failure.
