qlcnic: dcb: default to returning -EOPNOTSUPP
[ Upstream commit 1521db37f0d42334a88e8ff28198a27d1ed5cd7b ]
Clang static analysis reports this issue
qlcnic_dcb.c:382:10: warning: Assigned value is
garbage or undefined
mbx_out = *val;
^ ~~~~
val is set in the qlcnic_dcb_query_hw_capability() wrapper.
If there is no query_hw_capability op in dcp, success is
returned without setting the val.
For this and similar wrappers, return -EOPNOTSUPP.
Fixes: 14d385b99059 ("qlcnic: dcb: Query adapter DCB capabilities.")
