Subject: [PATCH][next] drivers: net: xgene: remove redundant assignment to variable offset

The variable offset is being initialized with a value that is never
read, it is being re-assigned later on in either path of an if
statement before being used. The initialization is redundant and
can be removed.

Cleans up clang scan build warning:
drivers/net/ethernet/apm/xgene/xgene_enet_cle.c:736:2: warning: Value
stored to 'offset' is never read [deadcode.DeadStores]
