accel/amdxdna: Return error when setting clock failed for npu1
[ Upstream commit 0c2768bf818904db705ff18674f771c3c4d8bbca ]
Due to miss returning error when setting clock, the smatch static
checker reports warning:
drivers/accel/amdxdna/aie2_smu.c:68 npu1_set_dpm()
error: uninitialized symbol 'freq'.
Fixes: f4d7b8a6bc8c ("accel/amdxdna: Enhance power management settings")
