qlcnic: remove set but not used variables 'op, cmd_op'

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

drivers/net/ethernet/qlogic/qlcnic/qlcnic_sriov_pf.c:1070:5: warning:
 variable 'op' set but not used [-Wunused-but-set-variable]
drivers/net/ethernet/qlogic/qlcnic/qlcnic_sriov_pf.c:1342:5: warning:
 variable 'cmd_op' set but not used [-Wunused-but-set-variable]

'op' never used since introduction in commit 7cb03b23 ("qlcnic:
Support VF-PF communication channel commands.")
'cmd_op' not used since commit 6226204b ("qlcnic: Fix operation
type and command type.")
