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

[Zheng Yongjun]

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

drivers/net/ethernet/microchip/lan743x_main.c: In function lan743x_pm_suspend:
drivers/net/ethernet/microchip/lan743x_main.c:3041:6: warning: variable ‘ret’ set but not used [-Wunused-but-set-variable]

`ret` is never used, so remove it.
