net: airoha: Fix non-standard return value in airoha_ppe_get_wdma_info()

airoha_ppe_get_wdma_info() returns -1 when the last path in the
forwarding path stack is not of type DEV_PATH_MTK_WDMA. This is not
a standard kernel error code. Replace it with -EINVAL since the
input path type is invalid from the caller's perspective.
