net: hns3: add return value for mailbox handling in PF

[ Upstream commit c59d606296842409a6e5a4828235b0bd46b12bc4 ]

Currently, there are some querying mailboxes sent from VF to PF,
and VF will wait the PF's handling result. For mailbox
HCLGE_MBX_GET_QID_IN_PF and HCLGE_MBX_GET_RSS_KEY, it may fail
when the input parameter is invalid, but the prototype of their
handler function is void. In this case, PF always return success
to VF, which may cause the VF get incorrect result.

Fixes it by adding return value for these function.

Fixes: 532cfc0df1e4 ("net: hns3: add a check for index in hclge_get_rss_key()")
