qlcnic: fix a return in qlcnic_dcb_get_capability()
[ Upstream commit c94f026fb742b2d3199422751dbc4f6fc0e753d8 ]
These functions are supposed to return one on failure and zero on
success. Returning a zero here could cause uninitialized variable
bugs in several of the callers. For example:
drivers/scsi/cxgbi/cxgb4i/cxgb4i.c:1660 get_iscsi_dcb_priority()
error: uninitialized symbol 'caps'.
Fixes: 48365e485275 ("qlcnic: dcb: Add support for CEE Netlink interface.")
