The value stored to mask in the calculations this patch removes is
not used, so the calculation and the assignment can be removed.

Cleans up the following clang-analyzer warning:

drivers/net/ethernet/netronome/nfp/flower/offload.c:1230:3: warning:
Value stored to 'mask' is never read
[clang-analyzer-deadcode.DeadStores].

Seems cleaner to always move ext and mask, in case some code 
is added later in the function and starts accessing mask.
