[PATCH net-next] net: qlogic: Remove set but not used variable

[Zheng Yongjun]

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

drivers/net/ethernet/qlogic/qlcnic/qlcnic_83xx_hw.c: In function qlcnic_83xx_cam_unlock:
drivers/net/ethernet/qlogic/qlcnic/qlcnic_83xx_hw.c:661:6: warning: variable ‘val’ set but not used [-Wunused-but-set-variable]

`val` is never used, so remove it.
