soc: qcom: smp2p: Fix fallback to qcom,ipc parse

Browse Source 
mbox_request_channel() returning value was changed in case of error.
It uses returning value of of_parse_phandle_with_args().
It is returning with -ENOENT instead of -ENODEV when no mboxes property
exists.

Fixes: 24fdd5074b ("mailbox: use error ret code of of_parse_phandle_with_args()")
