Subject: [PATCH net-next 14/15] e1000e: remove the redundant value assignment in e1000_update_nvm_checksum_spt

From: Kaixu Xia <kaixuxia@...cent.com>

Both of the statements are value assignment of the variable act_offset.
The first value assignment is overwritten by the second and is useless.
Remove it.
