Subject: [PATCH linux-next] e1000e: Remove redundant statement

This assignment statement is meaningless, because the statement
will execute to the tag "set_itr_now".

The clang_analyzer complains as follows:

drivers/net/ethernet/intel/e1000e/netdev.c:2552:3 warning:

Value stored to 'current_itr' is never read.
