[PATCH net-next] net: mvpp2: cls: Remove set but not used variable 'act'

[YueHaibing]

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

drivers/net/ethernet/marvell/mvpp2/mvpp2_cls.c: In function 
'mvpp2_cls_c2_build_match':
drivers/net/ethernet/marvell/mvpp2/mvpp2_cls.c:1159:28: warning:
 variable 'act' set but not used [-Wunused-but-set-variable]

It is never used since introduction in
commit 90b509b39ac9 ("net: mvpp2: cls: Add Classification offload support")
