Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/ethernet/ibm/ehea/ehea_qmr.c: In function 'ehea_create_cq':
drivers/net/ethernet/ibm/ehea/ehea_qmr.c:127:7: warning: variable 'cq_handle_ref' set but not used [-Wunused-but-set-variable]
drivers/net/ethernet/ibm/ehea/ehea_qmr.c:126:15: warning: variable 'epa' set but not used [-Wunused-but-set-variable]

They are never used since commit
