Zilin Guan 2537089413 i3c: dw: Fix memory leak in dw_i3c_master_i2c_xfers() 
The dw_i3c_master_i2c_xfers() function allocates memory for the xfer
structure using dw_i3c_master_alloc_xfer(). If pm_runtime_resume_and_get()
fails, the function returns without freeing the allocated xfer, resulting
in a memory leak.

Add a dw_i3c_master_free_xfer() call to the error path to ensure the
allocated memory is properly freed.

Compile tested only. Issue found using a prototype static analysis tool
and code review.
